AB  - Transition-metal activated phosphors are an important family of luminescent materials that can produce white light with an outstanding color rendering index and correlated color temperature for use in light-emitting diodes.  In recent years, work in this quite “hot” research field has focused on the development of Mn2+ and Mn4+ activated red phosphors. In this review article, we provide an overview of recent studies on Mn2+ and Mn4+ doped phosphors, including detailed synthesis routes (solid-state reaction and wet-chemical synthesis) and description of luminescence mechanisms and phosphors’ behaviors; discuss their promising applications in white light-emitting diodes; and present an extensive list of references to representative works in this field.

AB  - Herein, fine powders of yellow pigments based on BiVO4 were successfully prepared in two crystalline forms, tetragonal zircon-structured and monoclinic scheelite-structured, through a ethylene glycol-assisted method subjected to a thermal treatment at two different temperatures. The obtained materials were brightly colored with different hues of yellow, exhibited high reflection in the near-infrared region and showed visible luminescence under excitation by UV light. The new preparation method had a considerable effect on chromatic properties of the prepared scheelite-structured BiVO4 pigments. The sample with the most vivid and bright shade of yellow was found to have the L*a*b* and L*C* ab h* ab color coordinates of (87.28, 0.37, 91.53) and (87.28, 91.53, 89.79), which are indicative of exceptionally good chromatic properties superior and/or comparable to those of other inorganic yellow pigments, both commercially available and recently described. In addition, the NIR reflectance of this powder was very high (≥ 80%). © 2018 Elsevier Ltd and Techna Group S.r.l.

AB  - Dy3+-and Nd3+-doped YNbO4 powders were prepared using a mechanochemical method followed by annealing, and their photoluminescent properties were examined to assess the possibility of their use in phosphor thermometry. Luminescence intensity ratio technique was used as a temperature readout scheme for both YNba(4):Dy3+ and YNbO4:Nd3+ samples. The crystalline structure of the samples is confirmed by XRD measurements, while SEM was used for the microstructural and compositional characterization. Sample doped with Dy3+ ions emitting in the blue region has been investigated in the 293-773 K temperature range and exhibits maximal relative sensitivity of 1.97% K-1 at 300 K. YNbO4:Nd3+ sample showed intense NIR emission which fall into the first biological window. When heated from 303 up to 473 K relative temperature sensitivity of 0.28%K-1 at 300 K was achieved. Values of temperature sensitivities show that YNbO4 has a large potential for the development of thermographic phosphors in the blue and NIR spectral ranges when doped with trivalent Dy and Nd, respectively.

AB  - MgTiO3 nanoparticles doped with Mn4+, with homogeneous size ranging about 63.1 ± 9.8 nm, were synthesized by a molten salt assisted sol gel method. These nanoparticles have been investigated as optical thermal sensors. The luminescence of tetravalent manganese ion in octahedral environment within the perovskite host presents drastic variations with temperature. Three different thermometry approaches have been proposed and characterized. Two luminescence intensity ratios are studied. Firstly between the two R-lines of Mn4+ emission at low temperature (-250 °C and -90 °C) with a maximal sensitivity of 0.9% °C-1, but also secondly between 2E → 4A2 (R-line) and the 4T2 → 4A2 transitions. This allows studying the temperature variation within a larger temperature range (-200 °C to 50 °C) with a sensitivity between 0.6% °C-1 and 1.2% °C-1 over this range. The last proposed method is the study of the lifetime variation versus temperature. The effective lifetime value corresponds to a combination of transitions from two excited energy levels of the tetravalent manganese (2E and 4T2) in thermal equilibrium toward the fundamental 4A2 state. Since the more energetic transition (4T2 → 4A2) is spin-allowed, contrary to the 2E → 4A2 one, the lifetime drastically decreases with the increase in temperature leading to an impressive high sensitivity value of 4.1% °C-1 at 4 °C and an exceptional temperature resolution of 0.025 °C. According to their optical features, MgTiO3:Mn4+ nanoparticles are indeed suitable candidates for the luminescence temperature probes at the nanoscale over several temperature ranges.

AB  - This paper describes the processing, microstructure, optical and electrical properties of the nanocrystalline (NC) niobium and zinc doped titanium-tin-oxide (TTO:NZ) based ceramics. Variety of techniques was employed (X-ray diffraction, scanning electron microscopy, energy dispersive, Raman and impedance spectroscopy) in the characterization of the obtained TTO:NZ, which confirmed the formation of NC solid-solution matrix with Ti0.8Sn0.2O2 composition. A specific highly dense (approximately 97% of the theoretical density was reached) varistor like microstructure (matrix metal-oxide grains surrounded by the grain-boundary regions) and accordingly resembling electrical properties (breakdown electric field of approximately 130 V/mm and nonlinearity coefficient of α ≈ 6.5) were achieved through double cation doping and elected condition of the mechanochemical solid-state synthesis. Impedance response analysis of TTO:NZ ceramics by means of an equivalent electrical circuit based on the brick-layer model for polycrystalline materials revealed the presence of two temperature dependent electrical relaxation phenomena of the non-Debye type as well as the negative temperature coefficient of resistance behavior.

AB  - Herein, the synthesis, structural and crystal field analysis and optical spectroscopy of Mn4+ doped metal titanates ATiO(3) (A = Ca, Mg) are presented. Materials of desired phase were prepared by molten salt assisted sol-gel method in the powder form. Crystallographic data of samples were obtained by refinement of X-ray diffraction measurements. From experimental excitation and emission spectra and structural data, crystal field parameters and energy levels of Mn4+ in CaTiO3 and MgTiO3 were calculated by the exchange charge model of crystal-field theory. It is found that crystalline field strength is lower (Dq = 1831 cm(-1)) in the rhombohedral Ilmenite MgTiO3 structure due to the relatively longer average Mn4+-O2- bond distance (2.059 angstrom), and higher (Dq = 2017 cm(-1)) in orthorhombic CaTiO3 which possess shorter average Mn4+-O2- bond distance (1.956 angstrom). Spectral positions of the Mn(4+2)Eg - GT (4)A(2g) transition maxima is 709 nm in MgTiO3 and 717 nm in CaTiO3 respectively in good agreement with calculated values. (C) 2017 Elsevier B.V.

AB  - Temperature is important because it has an effect on even the tiniest elements of daily life and is involved in a broad spectrum of human activities. That is why it is the most commonly measured physical quantity. Traditional temperature measurements encounter difficulties when used in some emerging technologies and environments, such as nanotechnology and biomedicine. The problem may be alleviated using optical techniques, one of which is luminescence thermometry. This paper reviews the state of luminescence thermometry and presents different temperature read-out schemes with an emphasis on those utilizing the downshifting emission of lanthanide-doped metal oxides and salts. The read-out schemes for temperature include those based on measurements of spectral characteristics of luminescence (band positions and shapes, emission intensity and ratio of emission intensities), and those based on measurements of the temporal behavior of luminescence (lifetimes and rise times). This review (with 140 references) gives the basics of the fundamental principles and theory that underlie the methods presented, and describes the methodology for the estimation of their performance. The major part of the text is devoted to those lanthanide-doped metal oxides and salts that are used as temperature probes, and to the comparison of their performance and characteristics.

The problem may be alleviated using optical techniques, one of which is luminescence thermometry. This paper reviews the state of luminescence thermometry and presents different temperature read-out schemes with an emphasis on those utilizing the downshifting emission of lanthanide-doped metal oxides and salts. The read-out schemes for temperature include those based on measurements of spectral characteristics of luminescence (band positions and shapes, emission intensity and ratio of emission intensities), and those based on measurements of the temporal behavior of luminescence (lifetimes and rise times). This review (with 140 references) gives the basics of the fundamental principles and theory that underlie the methods presented, and describes the methodology for the estimation of their performance. The major part of the text is devoted to those lanthanide-doped metal oxides and salts that are used as temperature probes, and to the comparison of their performance and characteristics.",

AB  - This work explores the influence of annealing temperature on the structure and luminescence of 2 at% Eu3+ and 1 at Sm3+-doped Mg2TiO4 nanopowders produced via Pechini-type polymerized complex route. Mg2TiO4 samples were annealed at 7 different temperatures (400 degrees C, 450 degrees C, 500 degrees C, 550 degrees C, 600 degrees C, 650 degrees C and 700 degrees C) to determine the temperature range in which cubic inverse spinel structure is stable and to follow the changes of material luminescence properties. X-ray diffraction revealed that crystallization of both Eu3+ and Sm3+-doped Mg2TiO4 nanopowders starts at 400 degrees C, and that Sm3+ doped Mg2TiO4 starts to decompose at 650 degrees C, while Eu3+ doped Mg2TiO4 starts to decompose at 700 degrees C. Samples annealed at higher temperatures show higher crystallinity and larger crystallite size. Mg2TiO4 powder annealed at 600 degrees C is composed of similar to 5 nm size nanoparticles agglomerated in micron-size and dense chunks. The emission spectra of nanoparticles are composed of emissions from defects in Mg2TiO4 host and characteristic emissions of Eu3+ (D-5(0) - GT F-7(J)) and Sm3+ ((4)G(5/2) - GT H-6(J)) ions. The stronger emission and longer emission decays are observed with samples annealed at high temperatures. In the case of the Eu3+ ions emission intensity increased one order of magnitude between samples annealed at 400 degrees C and 650 degrees C. (C) 2015 Elsevier B.V. All rights reserved.

AB  - This paper reports on novel cobalt oxide nanoparticles (NPs) embedded in an amorphous silica (SiO2) matrix, synthesized using a modified sol-gel method. SEM and TEM images show as-synthesized particles to aggregate in the shape of spheres and less than 5 nm in size, while XRD and SAED analysis both point to well crystallized cubic spinel cobalt oxide phase with an average crystallite size of about 4.6 nm. Raman analysis confirms the formation of cobalt (III) oxide (Co3O4) NPs. As-synthesized Co3O4 single-nanocrystallite has magnetic properties that correlate with finite size effects and uncompensated surface spins. Temperature dependence of ZFC-FC magnetization curves reveals a sharp peak around 10 K which corresponds to the blocking temperature. A Curie-Weiss behavior of magnetization above 25 K shows lower Neel temperature of the sample compared with its bulk counterpart T-N=40 K (possibly due to crystal defects and nano-dimensionality of the particles). The magnetic measurements exhibit high magnetization at low temperatures (M-s=54.3 emu/g) which can be associated with random canting of the particles surface spins and uncompensated spins in the core which tends to interact ferromagnetically at low temperatures. The initial magnetization curve falls out from the hysteresis loop at 5 K, which could be also the effect of surface spins. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Yttrium aluminum garnet doped with rare earth ions (Ce3+, Eu3+ and Sm3+) was prepared by modified glycine method. Ce3+ as a dopant was used in four different concentrations (Y3-xCexAl5O12; x(%) = 1, 2, 3, 5), while doping concentration of Eu3+ and Sm3+ was Y3-xEuxAl5O12; x(%) = 3 and Y3-xSmxAl5O12; x(%) = 1, respectively. Phase composition of powders was investigated using XRD technique and expected target phase was confirmed. Photoluminescent characterization included measurements of excitation and emission spectra, as well as determination of emission decays. Y3-xCexAl5O12 shows intense broad-band emission, with maximum in green spectral region, at about 524 nm under ultraviolet or blue excitation. The origin of the luminescence is the 5d(1)- GT 4f(1) transition which is both parity and spin allowed. Ultraviolet and blue excitations of Eu3+ and Sm3+ doped Y3Al5O12 produce intense orange and red emissions. These emissions are phosphorescent in character and come from spin forbidden f-f electron transitions in Eu3+ and Sm3+ ions. For the case of Eu3+ doping emission comes mainly from D-5(0)- GT F-7(1) transitions with Stark components peaking at 590 nm and 590.75 nm, and with emission decay of 4.15 ms. In the case of Sm3+ doping, the emission spectrum, shows (4)G(5/2)- GT H-6(5/2), (4)G(5/2)- GT H-6(7/2), and (4)G(5/2)- GT H-6(9/2) transitions, with the most intense stark components positioned at 567.5 nm, 617 nm, and 650 nm, respectively and for transition centered at 617 nm, emission decay is 3.12 ms.

AB  - Nanocrystals of Y2O3 and La2O3 solid solutions were synthesized with a cubic bixbyite structure containing La2O3 content of up to 50 mol%. This is comparatively higher than that in bulk materials of the same structure, where La2O3 content of only 20 mol% can be obtained. A set of europium-doped (Y1-xLax)(2)O-3 (x=0.1, 0.2, 0.3, 0.4) cubic bixbyite solid solutions with crystallites of approximately 10 nm in size was prepared using the polymer complex solution method. Structural analysis was performed using X-ray diffraction measurements, Rietveld full profile refinement, and from Eu3+ luminescence emission. The energy levels of the Eu3+ ion, second order crystal field parameters, and crystal field strength were obtained for all compositions of solid solutions. We show that the crystal field parameters linearly depend on unit cell parameter and that these dependencies may be considered as part of an overall dependence for the entire sesquioxide family.

AB  - In this research we prepared nanocrystalline YNbO4:Eu3+ phosphor, i.e. nanophosphor, powder using an efficient mechanochemical method followed by annealing. X-ray diffraction analysis revealed that YNbO4:Eu3+ crystallizes in monoclinic structure C2/c where, from the point of view of A and B in ABO(4) compounds, cation coordination can be noted as [6+2, 4+2]. Crystallite size of about 40 nm, was estimated using Debye Scherrers equation. Raman spectroscopy with 785 and 532 rim excitation wavelengths is performed to record a majority of materials phonon modes and to provide more in depth understanding of the YNbO4 structure. Scanning electron microscopy observations indicate that the mechanical treatment during synthesis is causing non-uniformity of the powder microstructure. High resolution photoluminescent measurements upon UV excitation showed intense emission coming from f-f transitions of the europium ion with the lifetime of 0.68 ms, suggesting that the obtained YNbO4:Eu3+ is a good potential phosphor. A comparison of emissive properties with microcrystalline YNbO4:Eu3+ was made and it showed higher values of emission intensity and lifetime of the nanocrystalline sample.(C) 2014 Elsevier Ltd and Techna Group S.r.l.

AB  - We prepared Eu3+- and Sm3+-doped YNbO4 phosphor powders using a simple solid-state reaction method and examined their photoluminescence properties in order to investigate the possibility for their usage in phosphor thermometry. Photoluminescence measurements were performed in the temperature range 303-773 K, and the fluorescence intensity ratio of the paired emissions lines was studied as a function of temperature. The results have shown that YNbO4:Eu3+ possesses the absolute sensitivity of approximately 3 Chi 10(-3) K-1 at about 700 K, while relative sensitivity changes within the range of 0.5-2.7% K-1. YNbO4:Sm3+ has the maximum sensitivity of around 7 Chi 10(-4) K-1 at about 700 K with the relative sensitivity of 0.43% K-1 around 500 K. Calculated temperature sensitivities of samples show that these materials have a good potential for the development of therrnographic phosphors. Experimental lifetime measurements recorded at 303-773 K were fitted using a temperature dependent charge transfer model, TDCT. This model yields good agreement between experimental and fitted lifetime data. The sample crystalline structure is confirmed by XRD measurements. (C) 2014 Elsevier B.V. All rights reserved.

AB  - Eu3+-doped La2O3 nanocrystalline powder was prepared by polymer complex solution method and further used for preparation of Eu3+-doped La(OH)(3). Structural and optical characterization was carried out by powder X-ray diffraction and photoluminescent spectroscopy. XRD measurements confirmed the formation of hexagonal La2O3 and its recrystallization into La(OH)3 in a humid atmosphere. Excitation spectra show redshift of host lattice and charge transfer emission bands in La(OH)3 while bands that correspond to Eu3+- f-f transitions are placed at same wavelengths in both samples. Photoluminescence spectra recorded over the temperature range from 10 K to 300 K show that intensities of emission lines in Eu3+-doped La2O3 do not depend on temperature as much as in La(OH)3 sample. Observed dominant D-5(0) - GT :F-7(2) and markedly visible D-5(0)- GT F-7(0) emissions in doped La2O3 indicate that Eu3+ ion is located in a structural site without an inversion center. On the other hand, in Eu3+-doped La(OH)3 D-5(0)- GT F-7(0) transition is barely visible while D-5(0)- GT F-7(2) is not prominent, and with temperature drop three D-5(0)- GT F-7(j) (J=1, 2, 4) transitions become almost of the same intensity. In both La2O3 and La(OH)3 structures Eu3 ion replaces La3+ in non-centrosymmetric C-3v and C-3h crystallographic sites, respectively, and difference in symmetry of the crystal field around europium ion is explained by comparing shape and volume of these sites. Decay times of the 5D0- level recorded over the temperature range 10-300 K revealed that emission lifetime values in La2O3 (-0.7 ms) are almost two times higher than in La(OH)3 (-0.4 ms), and unlike in La2O3, lifetime in La(OH)(3) is temperature dependent.

AB  - Gadolinium-oxide nanopowders doped with Yb3+ and Ho3+ ions and co-doped with alkali metal ions (Li+ and Na+) were synthesized via the polymer complex solution method and their up-conversion emission properties are analyzed. Prepared powders were well crystallized in cubic bixbyite structure, without any impurity phases and with an average crystallite size of about 25 nm, as shown by X-ray powder diffraction analysis. No adsorbed species on the surface of nanoparticles were detected by infrared measurements. The particle morphology was analyzed by transmission electron microscopy, which revealed agglomerated crystalline nanoparticles with irregular, polygonal-like shapes, having a size in the range from 30 to 50 nm. Up-conversion emission properties of Gd2O3:Ho3+,Yb3+ nanopowders were evaluated from photoluminescence emission and decay measurements using 980 nm excitation. Two-photon up-conversion processes produced emissions in visible - near infrared spectral range, with the strongest green emission from F-5(4),S-5(2)- GT I-5(8) Ho3+ electronic transition, and weak red and near infrared from F-5(5)- GT I-5(8) and F-5(4), S-5(2) - GT I-5(7) transitions, respectively. In addition, three-photon up-conversion emission was detected in ultra-violet-blue spectral region ((5)G(4)- GT I-5(8), D-3(3)- GT I-5(6) and (5)G(5)- GT I-5(8) transitions). Luminescence measurements were performed on samples with different Ho3+ (0.5 and 1 at%) and Yb3+ (2, 4 and 6 at%) concentrations to find that 0.5 at% of Ho3+ and 2 at% of Yb3+ provides the most intense up-conversion emission. The influence of alkali metal (Li+ and Na+) ion co-doping is studied on the sample that showed the most intense up-conversion emission. Increase in the intensity of up-conversion emission is observed for both Li+ and Na+ co-doping. The effect is more pronounced with Li, where addition of 5 at% of Li+ led to more than one order of magnitude emission enhancement. Alkali metal ion co-doping also significantly improved up-conversion color purity through considerably larger increase of green emission compared to red and near infrared. (C) 2013 Elsevier B.V.

AB  - In this report, a cost- and time-effective method for synthesis of Y2O3:Yb3+, Er3+ nanoparticles that exhibit up-conversion emission under infrared excitation is presented. The synthesis method is based on the self-propagating, room-temperature reaction between metal nitrates and sodium hydroxide, and a subsequent calcination process. Series of samples were prepared with calcinations at various temperatures (600 degrees C, 800 degrees C and 1100 degrees C) for 1 h, and also with different Yb3+-Er3+ ratios (10:1, 5:1 and 2:1). All calcined samples crystallized in a cubic bixbyite crystal phase with crystallite size from 12 to 44 nm in diameter, for samples calcined at 600 degrees C and 1100 degrees C, respectively. Different nanoparticle morphologies were obtained after calcinations on different temperatures; at temperatures under 1100 degrees C rod-like particles were obtained, while at 1100 degrees C spherical particles were formed. In all samples up-conversion emissions and corresponding lifetimes were measured after excitation in room temperature at 978 nm. The most intense emission originates from the characteristic intra-shell f-f electronic transitions of Er3+ ions: [2H(9/2)- GT I-4(15/2)] in blue (407-420 nm); [(H-2(11/2), S-4(3/2))- GT I-4(15/2)] green: 510-590 nm; and [F-4(9/2)- GT I-4(15/2)] in red (640-720 nm) spectral regions.

AB  - In this report, structure, morphology and luminescence of Y2O3:Sm3+ nanoparticles prepared by self-propagating room temperature reaction are presented. This new, simple and cost effective synthesis allows obtaining desired phase composition by mixing appropriate amounts of yttrium and samarium nitrates together with sodium hydroxide. A set of samples is prepared with different Sm3+ concentrations (0.1, 0.2, 0.5, 1 and 2 at %) in order to observe changes of luminescence properties. Also, effects of post synthesis annealing at several temperatures (600 degrees C, 800 degrees C and 1100 degrees C) are analyzed. For all samples X-ray diffraction showed that powders have cubic bixbyite structure (I alpha-3), and TEM analysis showed particles of less than 100 nm. Luminescence emission spectra clearly show peaks characteristic for electronic spin-forbidden transition of Sm3+ ions (4)G(5/2)- GT H-6(5/2), H-6(7/2) and H-6(9/2) centered at 578, 607 and 654 nm, respectively. Emission lifetime values decrease with Sm3+ ion concentration increment, from 1.94 ms for 0.1 at% to 0.97 ms for 2 at%. In addition, enlargement of lifetime value is observed when thermal treatment is done at the highest temperature due to the elimination of luminescence quenching species from the surface of particles.

Also, effects of post synthesis annealing at several temperatures (600 degrees C, 800 degrees C and 1100 degrees C) are analyzed. For all samples X-ray diffraction showed that powders have cubic bixbyite structure (I alpha-3), and TEM analysis showed particles of less than 100 nm. Luminescence emission spectra clearly show peaks characteristic for electronic spin-forbidden transition of Sm3+ ions (4)G(5/2)- GT H-6(5/2), H-6(7/2) and H-6(9/2) centered at 578, 607 and 654 nm, respectively. Emission lifetime values decrease with Sm3+ ion concentration increment, from 1.94 ms for 0.1 at% to 0.97 ms for 2 at%. In addition, enlargement of lifetime value is observed when thermal treatment is done at the highest temperature due to the elimination of luminescence quenching species from the surface of particles.",

AB  - Phosphor materials are of special interest due to their important applications ranging from solid state lightning and displays to biomedicine. Understanding the spectroscopic properties of these materials is important for optimizing their emission for technological applications. Zinc silicate (Zn2SiO4) has been identified as a very suitable host matrix for many rare-earth and transition metal dopant ions with excellent luminescent properties in the blue, green and red spectral zones. Here, we present high resolution measurements of low-temperature photoluminescence of trivalent europium doped zinc silicate particles prepared by combination of so-gel and combustion synthesis route. We observed and analyzed 5D(0) - GT F-7(J) spin forbidden f-f electronic transitions at low temperatures, as well as emission kinetics from D-5(0) level and lifetime-temperature dependence.

AB  - Recently, trivalent rare earth doped materials have received significant attention due to the strong temperature dependence of the fluorescence emission of these materials, which can be useful in temperature sensing. Here, we investigated Y2O3 ceramic powders doped with Yb3+ and co-doped with either Tm3+ or Ho3+. The powders were obtained via spray pyrolysis at 900 degrees C and additionally thermally treated at 1100 degrees C for 24 h. Structural characterization using X-ray powder diffraction confirmed the cubic bixbyte structure. Scanning electron microscopy (SEM) revealed that the particles exhibit a uniform spherical morphology. The up-conversion emissions were measured using laser excitation at 978 nm, resulting in the following transitions: blue emission in the range of 450-500 nm, weak red emission in the range of 650-680 nm and near infrared emission in the range of 765-840 nm for Tm3+, as well as green emission centered at 550 nm and weak near infrared emission at 755 nm for the Ho3+ ions. In addition, the temperature dependence of the fluorescence intensity ratios of different Stark components was analyzed in the range of 10-300 K. Significant temperature sensitivity was detected for several components, with the largest value of 0.097 K-1 related to the intensity ratio of I-536 and I-772 emissions observed for the Y2O3:Yb,Ho powder.

AB  - New red sesquioxide phosphor, Eu(3+)doped (Y0.5La0.5)(2)O-3, was synthesized in the form of nanocrystalline powder with excellent structural ordering in cubic bixbyite-type, and with nanoparticle sizes ranging between 10 and 20 nm. Photoluminescence measurements show strong, Eu3+ characteristic, red emission (x = 0.66 and y = 0.34 CIE color coordinates) with an average D-5(0) emission lifetime of about 1.3 ms. Maximum splitting of the F-7(1) manifold of the Eu3+ ion emission behaves in a way directly proportional to the crystal field strength parameter, and experimental results show perfect agreement with theoretical values for pure cubic sesquioxides. This could be used as an indicator of complete dissolution of Y2O3 and La2O3, showing that (Y0.5La0.5)(2)O-3:Eu3+ behaves as a new bixbyite structure oxide, M2O3, where M acts as an ion having average ionic radius of constituting Y3+ and La3+. Emission properties of this new phosphor were documented with detailed assignments of Eu3+ energy levels at 10 K and at room temperature. Second order crystal field parameters were found to be B-20 = -66 cm(-1) and B-22 = -665 cm(-1) at 10 K and B-20 = -78 cm(-1) and B-22 = -602 cm(-1) at room temperature, while for the crystal field strength the value of 1495 cm(-1) was calculated at 10 K and 1355 cm(-1) at room temperature.

AB  - Rare earth (RE) oxides are important hosts for the luminescence of RE activators with numerous practical applications in light-emitting devices. In this work, we investigated the possibility for Gd2O3: Eu3+ usage in phosphor thermometry by observing the temperature changes of trivalent europium ion transitions from the D-5(0) and D-5(1) energy levels to the ground-state levels. A set of three samples of Eu3+-doped Gd2O3 (1, 5 and 10 at.% Eu3+) was produced via combustion synthesis. The sample crystalline structure is confirmed by XRD measurements. The intensity ratio of the two emission lines was studied as a function of temperature in the temperature range 300-800 K, and lifetime was measured in the interval 10-800 K. All three Gd2O3: Eu3+ samples proved to have good potential for the development of thermographic phosphors.

AB  - Rare-earth orthovanadates are important hosts for the luminescence of rare earth activators with considerable practical applications in the artificial production of light. In this paper we investigated the possibility for GdVO4:Sm3+ usage in phosphor thermometry by observing the temperature changes of trivalent samarium transitions from F-4(3/2) and (4)G(5/2) energy levels to the ground state. A set of three samples of Sm3+-doped GdVO4 (0.5, 1 and 2 mol.% Sm3+ with respect to Gd3+ ions) was produced via solid state synthesis. The sample crystalline structure is confirmed from x-ray diffraction (XRD) measurements. Photoluminescence measurements were recorded in the temperature range 293-823 K and the fluorescence intensity ratio of the paired emissions bands was studied as a function of temperature. All three GdVO4:Sm3+ samples proved to have good potential for the development of thermographic phosphors, whereas the maximum sensitivity of approximately 4.5x10(-4) K-1 was found for the sample with 2 mol.% Sm3+ in the temperature region around 750 K.

AB  - Lithium-indium oxide is a high-density (5.9 g center dot cm(-3)), wide band-gap semiconductor with promising applications for scintillating detection of solar neutrinos as well as for efficient phosphorescence when doped with Er3+ or Sm3+ ions. In this report, we demonstrate visible upconversion emission of Er3+-doped LiInO2 synthesized by a simple solid-state chemistry procedure and discuss mechanisms responsible for pumping the Er3+ ions to upper levels. Intense upconversion emission is observed in the green and red spectral regions under near-infrared excitation, and it is greatly enhanced by co-doping with Yb3+ ions. We also examined the upconversion intensity change as a function of temperature, and, consequently, possible applications of this material as a low-temperature sensor.

AB  - Samples of Lu2O3:Eu3+ (3 at. % Eu) and Lu2O3:Sm3+ (1 at. % Sm), were prepared via the polymer complex solution method using poly(ethylene glycol) as the fuel and as nucleation agent for crystallization process. Knowing that lutetium oxide has high chemical stability and temperature resistance, in this study, the possibility for its application in high-temperature phosphor thermometry was investigated. This non-contact technique uses the thermal dependence of phosphor fluorescence to measure temperature remotely. The structural and morphological properties were investigated by X-ray powder diffraction (XRPD) analysis and transmission electron microscopy (TEM). The obtained results confirmed that this synthesis yields the desired crystalline structure with particle sizes in the range from 30 to 50 nm. Photoluminescence emission measurements were recorded in the temperature range from ambient up to 873 K. The obtained results demonstrated the performance of Eu3+- and Sm3+-doped Lu2O3 as high temperature thermographic phosphors of very good sensitivity.
