AB  - Herein, we demonstrate the photoluminescence properties of Dy3+-activated YNbO4, LuNbO4, and mixed YxLu1−xNbO4:Dy3+ (x=0.25, 0.5, 0.75) phosphors. For this purpose, fve samples with a fxed Dy3+ concentration (2 mol%) were prepared by the solid-state reaction method. X-ray difraction measurements showed that all phosphors crystallize in a monoclinic fergusonite-beta-(Y) structure with a C2/c space group. Scanning electron microscopy clearly shows that samples are composed of dense, well-developed micron-sized, cube-shaped grains with rounded edges. The photoluminescent emission spectra feature Dy3+ peaks at standard positions corresponding to transitions from the 4 F9/2 excited emitting level to the 6 HJ (J=15/2; 13/2; 11/2 and 9/2) lower levels with two dominant emission bands placed in the blue (~479 nm, B) and yellow (~576 nm, Y) spectral region. It is observed that with Lu increase in the host lattice Y/B ratio decreases toward the desired ratio of unity to obtain white light. To evaluate the suitability of these phosphors for use in solid-state lighting, their photoluminescence emission was analyzed in detail by calculating CIE coordinates, correlated color temperature (CCT) and Delta u,v (DUV). It is shown that CIE chromaticity coordinates of all Dy3+-activated YxLu1−xNbO4 samples (x=0, 0.25, 0.5, 0.75, and 1) fall into the white portion of the diagram and that with the increase of Lu in the host lattice color becomes whiter. CCT values for all samples are in the cooler 4000–4500 K range with positive DUVs indicating that color points are placed above the black body curve. The average lifetime of 4 F9/2 level is calculated to be~0.2 ms for all Dy3+-activated YxLu1−xNbO4 samples, indicating that there is no infuence of the Y-to-Lu ratio in the host niobate material on the luminescence kinetics.

Judd–Ofelt intensity parameters show a slight increase with rising concentration, up to Ω2 = 8.13∙10−20 cm2, Ω4 = 2.67∙10−20 cm2, and Ω6 is concentration invariant with the 0.35∙10−20 cm2 value. Emission lifetimes of the 5D0 state are almost constant with ∼0.6 ms, and a slight decrease is observed with the highest concentrations. The intrinsic quantum yield of all the samples is about 0.5.

AB  - Luminescent Eu3+-doped SrF2 nanoparticles were synthesized using microwave-assisted synthesis. Their surfaces were modified either by polyethylene glycol or mercaptopropionic acid to enhance their dispersibility in aqueous media and colloidal formation. X-ray diffraction analysis confirmed single-phase cubic structure in both types of hydrophilic-modified Sr0.9Eu0.1F2 luminescent powders. The average crystallite size of nanoparticles is found to be ∼13 nm. Scanning electron microscopy of the representative PEG2000-modified sample revealed that particles form agglomerates composed of densely packed nanoparticles. The microstructure at a local level was investigated by transmission electron microscopy showing the presence of sphere-like nanoparticles with an average particle size of 12.5 nm and 14 nm for PEG-modified and MPA-modified Sr0.9Eu0.1F2, respectively. Both PEG2000 and MPA-modified Sr0.9Eu0.1F2 water dispersions show strong red Eu3+ emission under 405 nm excitation that is quenched in the presence of the primary NP fertilizer, ammonium dihydrogen phosphate, NH4H2PO4. The limit of detection was calculated to be ∼19 mM for both hydrophilic-modified Sr0.9Eu0.1F2 luminescent nanoparticles.

AB  - Eu3+-doped YxLu1−xNbO4 (x = 0, 0.25, 0.5, 0.75, 1) were prepared by the solid-state reaction method. YNbO4:Eu3+ and LuNbO4:Eu3+ crystallize as beta-Fergusonite (SG no. 15) in 1–10 μm diameter particles. Photoluminescence emission spectra show a slight linear variation of emission energies and intensities with the solid-solution composition in terms of Y/Lu content. The energy difference between Stark sublevels of 5D0→7F1 emission increases, while the asymmetry ratio decreases with the composition. From the dispersion relations of pure YNbO4 and LuNbO4, the refractive index values for each concentration and emission wavelength are estimated. The Ω2 Judd–Ofelt parameter shows a linear increase from 6.75 to 7.48 × 10−20 cm2 from x = 0 to 1, respectively, and Ω4 from 2.69 to 2.95 × 10−20 cm2. The lowest non-radiative deexcitation rate was observed with x = 1, and thus LuNbO4:Eu3+ is more efficient phosphor than YNbO4:Eu3+.

AB  - Y3NbO7:xEu3+ powders (x = 0.25, 0.5, 0.75, 2, 3, 5, 10 at%) were synthesized by a two-step vibrational milling, alternating with annealing. All the samples crystallize as fluorite-type structure (space group Fm3‾m), with crystallite size 50–60 nm and show a strong orange/red luminescence with an excited state lifetime around 1.2 ms. Photoluminescence excitation and emission spectra show rapid intensity decline after 3 at% of Eu3+ content, indicating this concentration as critical for the concentration quenching, and we predicted multipolar interaction as the dominant mechanism behind it. Judd–Ofelt intensity parameters (Ω2 = 0.941∙10−20 cm2, Ω4 = 0.277∙10−20 cm2, Ω6 = 0.277∙10−20 cm2) were obtained from the excitation spectrum of Y3NbO7:3 at%Eu3+. The emission of this luminescent powder is characterized by radiative and nonradiative lifetimes of 2.3 ms and 2.4 ms, respectively, and an intrinsic quantum yield of 51.5%.

abstract = "Y3NbO7:xEu3+ powders (x = 0.25, 0.5, 0.75, 2, 3, 5, 10 at%) were synthesized by a two-step vibrational milling, alternating with annealing. All the samples crystallize as fluorite-type structure (space group Fm3‾m), with crystallite size 50–60 nm and show a strong orange/red luminescence with an excited state lifetime around 1.2 ms. Photoluminescence excitation and emission spectra show rapid intensity decline after 3 at% of Eu3+ content, indicating this concentration as critical for the concentration quenching, and we predicted multipolar interaction as the dominant mechanism behind it. Judd–Ofelt intensity parameters (Ω2 = 0.941∙10−20 cm2, Ω4 = 0.277∙10−20 cm2, Ω6 = 0.277∙10−20 cm2) were obtained from the excitation spectrum of Y3NbO7:3 at%Eu3+. The emission of this luminescent powder is characterized by radiative and nonradiative lifetimes of 2.3 ms and 2.4 ms, respectively, and an intrinsic quantum yield of 51.5%.",

AB  - The Mn5+-activated Ca6Ba(PO4)4O phosphor is described in this paper as a versatile nearinfrared luminescence thermometry probe in a physiological temperature range. It is focused on several steady-state approaches to luminescence thermometry operating entirely in the first (excitation ex=635 nm) and the second (emission) biological transparency windows. This material was synthesized by a solid-state reaction using CaCO3, BaCO3, (NH4)H2PO4 and MnO as precursor materials. Starting chemicals were thoroughly mixed in an agate mortar for 1 hour with an appropriate amount of etanol. A mixture of the raw materials was heated at 600⁰C for 6 hours, ground in an agate mortar, and further calcinated at 1280⁰C for 10h. The exploited features of Ca6Ba(PO4)4O:Mn5+ emission spectra were (Figure 1): i) luminescence intensity ratio (LIR) between spin-allowed 3T2 → 3A2 and spin forbidden 1E → 3A2 (Sr MAX=2.04%K-1 @ 20 oC, dT<0.36 K); ii) LIR between Stokes peak corresponding to the bending deformation vibronic mode (O-Mn-O) and spin forbidden 1E → 3A2 (Sr MAX=0.57 %K-1 @ 100 oC, dT<2 K above 50 oC); iii) LIR between Stokes and Anti-Stokes peaks corresponding to the bending deformation vibronic mode (O-Mn-O) (Sr MAX=0.52 %K-1 @ 100 oC, dT3 K); iv) red-shift of the position of the 1E → 3A2 peak (Sa=0.21 cm-1K -1, dT<0.33 K) and v) the broadening of the full with at half maximum (FWHM) of the same peak with the temperature increase (Sr MAX=0.34 %K-1 @ 100 oC, dT<0.38 K). The steady-state approach facilitated quick measurements of emission spectra and, consequently, a large number of acquired spectra (50) for each temperature point, which were used to experimentally determine the temperature resolution for each thermometry method.

AB  - Lanthanide (Ln) activated phosphors are a major topic in both basic and applied science. The trivalent europium ion (Eu3+) is well recognized for its intense luminescence in the orange/red spectral region, making it useful for a wide range of applications. Because Eu3+ has an even number of electrons in its 4f shell ([Xe]4f 6 ), the ion has non-degenerated ground (7F0) and excited (5D0) energy states, as well as non-overlapping 2S+1LJ multiplets, resulting in emission spectra that are predictable in relation to the host material site symmetry. The solid-state reaction synthesis method was used to make a set of five Eu-doped YxLu1- xNbO4 samples (x=0–1) with a fixed Eu concentration (5%). All the structures crystallize as beta-Fergusonite, in which the Eu ion replaces the Y or Lu ion in a large, low-symmetry octahedron. The excitation and emission spectra of the Eu3+ ion in all composition hosts show characteristic f-f transitions from which Stark energy levels were calculated. Specific features and energy positions of the distinctive 5D0→7F1 magnetic dipole transition were determined when measured with higher resolution and spectra deconvolution was utilized. The maximum ΔE splitting of the 7F1 manifold's Stark splitting and the asymmetry ratio R all show Y/Lu content-dependent trends. Calculations based on Judd-Ofelt theory were utilized to determine specific quantities. The lowest non-radiative deexcitation rate was observed with x = 1, resulting in the conclusion that LuNbO4 is a better host-matrix for Eu3+ emission than other compositions.

AB  - A promising lithium-indium-oxide (LiInO2) wide band-gap semiconductor for scintillating detection, photoluminescence, and photocatalysis [1-3] was prepared by a mechanochemical solid-state synthetic procedure that can be found elsewhere [3]. Its structure and morphology were investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. SEM images show agglomerates of relatively uniform size of around 300 nm spherical-shaped particles of LiInO2 powder, while the XRD pattern confirmed the formation of the nanocrystalline tetragonal structure withamdI /41 space group (no. 141) symmetry. Detailed vibration analysis, together with the assignments of the band modes, was performed through the best-fit match of the experimental and density functional theory (DFT) calculated Raman spectrum. Geometry optimizations and vibrational frequencies calculations were conducted using B97-1 functional correlation [4] and LanL2DZ was used as a basis set.

AB  - When activated by Dy3+, Na0.25K0.25Bi0.50TiO3 (NKBT), piezoelectric powders show strong luminescence in the blue and yellow spectral range. Emissions of this material can be effectively utilized for both luminescence intensity ratio and lifetime-based readouts of temperature. Photoluminescence measurements over a temperature range of 293–483 K show that the luminescence intensity ratio temperature readout has maximal relative sensitivity of 1.93% K−1 at 380 K, while the relative sensitivity of the lifetime temperature readout reaches 1.1% K−1 at 480 K. For this study, materials were synthesized by a solid-state reaction using TiO2, Bi2O3, Na2CO3, K2CO3 and Dy2O3 as precursors. X-ray diffraction measurements showed that the NKBT sample crystallized in the A-site substituted distorted perovskite rhombohedral structure (R3c symmetry). The photoluminescence spectra showed characteristic emission bands of Dy3+ ions centered at 457 nm (4I15/2 → 6H15/2), 478 nm (4F9/2 → 6H15/2), 574 nm (4F9/2 → 6H13/2) and 663 nm (4F9/2 → 6H11/2). The ratio of emissions from 4F9/2 and 4I15/2 excited states to the 6H15/2 ground state was used as a luminescence intensity ratio indicator of temperature, while the decay of emission from 4F9/2 → 6H13/2 transition was used as a lifetime indicator of temperature. CIE coordinates x = 0.326 and y = 0.361 calculated from room temperature emission spectra show the perspective of this material for use in white light emission devices.

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  - 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  - 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  - 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  - Lithium-indium oxide is one of the candidate materials as solid-state scintillators for solar neutrinos due to an inverse beta -decay of In-115 to Sn-115. On the other hand, when doped with rare-earth ions such as Eu3+ or Sm3+, it becomes a promising phosphor material. In this report we present a simple solid-state procedure for preparation of LiInO2:Eu3+ powders. X-ray diffraction confirmed product in tetragonal structural form (space group: I4(1)/amd) and no impurity phases were detected. Then, high resolution photoluminescence emission measurements were performed at room and low temperatures to find D-5(0) - GT F-7(J). Emission kinetics from D-5(0) level exhibited pure single exponential behavior with lifetime of about 1.5 ms. Maximum energy splitting of F-7(1) manifold is recorded as a function of temperature.

AB  - We present here the synthesis procedure for obtaining Zn2SiO4:M2+ (M = Mn, Ni, Co) powder based on the combination of so-gel and combustion methods. Combustion is performed both in a conventional furnace and in a microwave oven in order to evaluate the influence of combustion conditions on the properties of synthesized material. X-ray diffraction analysis confirmed that obtained material has crystallized in rhombohedral structure of Zn2SiO4 (willemite) with traces of ZnO. The effects of combustion conditions are investigated further by means of thermogravimetric analysis, differential thermal analysis, infrared spectroscopy, diffuse reflectance optical spectroscopy and photoluminescence spectroscopy. Based on these results we could conclude that microwave combustion synthesis can be successfully applied for Zn2SiO4-based products.
