AB  - Crystal phosphors have many unique advantages compared with powdery ones. Herein, room-temperature-grown millimeter-sized single-crystal phosphors of Cs2XF6:Mn4+ (X = Ge, Si, and Ti) with remarkably higher external quantum efficiency than the corresponding powdery samples are reported. In addition, as compared with the powdery ones, the crystal samples exhibit much better stability toward water under different pH conditions. The red light-emitting diodes (LEDs) based on Cs2XF6:Mn4+ crystals show significantly improved luminous efficiency than those based on their corresponding powders. An assembled white LED device composed of the two layers of phosphors, i.e., the crystal (such as Cs2GeF6:Mn4+) and commercial Y3Al5O12:Ce3+, on a blue chip exhibits intense warm white light with high luminous efficiency (up to 193 lm W−1), high color rendering indexes (88), and low correlated color temperatures (3107 K). Hence, these crystals with greatly improved efficiency and stability can be potentially applied in high-quality LED backlighting display and white LED lighting, especially inside the micro-LED devices. © 2019 WILEY-VCH Verlag GmbH & Co.

AB  - Judd-Ofelt analysis has been performed from the photoluminescence emission spectra of Y2O3:Eu3+ with 3%, 1% and 0.1% doping concentration and YVO4:Eu3+ with 1% doping concentration, in temperature range from 40 °C to 460 °C. For precise calculation, an extended Sellmeier equation that accounts for the doping concentration and temperature dependence of the refractive index of Y2O3 doped with lanthanides is estimated. The temperature dependence of Ω2 and Ω4 parameters are fitted with quadratic and linear regression, respectively. Judd-Ofelt intensity parameters uniformly drop with increasing temperature, but at a different rate for different doping concentrations. From the Judd-Ofelt parameters radiative lifetimes and emission cross-sections were calculated. The cross-sections show a linear decrease with increasing temperature. © 2019 Elsevier B.V.

AB  - Traditional applications of the Judd-Ofelt (JO) theory to the analysis of the Eu3+ optical spectra make use of the emission transitions originating from the 5D0 manifold. In the present paper, we report an alternative method of evaluating the JO intensity parameters from the Eu3+ emission spectra based on the 5D1 → 7F0,1 transitions. The reduced matrix elements of the unit tensor operators are re-calculated for the 5D0,1,2 → 7F0,1,…,6 Eu3+ transitions in the intermediate coupling approximation using the average electrostatic and spin-orbit coupling parameters. The suggested method was tested by analyzing the emission spectra of the Eu3+ doped GdAlO3, LaF3, NaYF4, Y2O3, ZrO2, YNbO4, ZBLA and PIGLZ hosts. It is shown that the developed method is more accurate for the hosts with relatively high 5D1 level population, which emphasizes its high potential and applicability. In addition to the JO analysis, the CIE chromaticity coordinates are calculated for the investigated spectra. © 2019 Elsevier B.V.

AB  - Wooden cultural heritage serves as a very important source of information for historians and researchers. Also, it imposes an obligation on the science to keep this legacy for future generations in a proper condition. Among other techniques of conservation of wooden cultural heritage, a very suitable method is impregnation of the wood with the polymer, whereby the wood/polymer composites are formed. This paper describes the method of preparing the wood/polymer composites based on beechwood, using five different monomer systems. The method of lyophilization and subsequent polymerization by gamma radiation was used. After lyophilization and immersing in the monomer solutions, the wood samples were dried and irradiated with a dose of 25 kGy and different gamma irradiation dose rates. The weight of the samples before and after this procedure was measured. Also, changes in the mechanical properties of wood (compression test) before and after treatment were examined. We also examined the effect of radiation dose rate on polymerization. Based on the weight differences, dose rates and materials characterization we determined which of the monomer solution and dose rate are the most suitable for making beechwood/polymer composites. © 2019 Elsevier Ltd

AB  - Titanium dioxide is a photocatalyst, known not only for its ability to oxidize organic contaminants, but also for its antimicrobial properties. In this article, significant enhancement of the antimicrobial activity of TiO2 (up to 32 times) was demonstrated after its activation by ball milling. The antimicrobial activity was analyzed for one fungal and 13 bacterial ATCC strains using the microdilution method and recording the minimum inhibitory concentration (MIC) values. In order to further investigate the correlation between the mechanical activation of TiO2 and its antimicrobial activity, the structure, morphology and phase composition of the material were studied by means of Electron Microscopy, X-ray diffraction and nitrogen adsorption-desorption measurements. UV-Vis diffuse reflectance spectra were recorded and the Kubelka-Munk function was applied to convert reflectance into the equivalent band gap energy (Eg) and, consequently, to investigate changes in the Eg value. X-ray photoelectron spectroscopy was used to analyze the influence of mechanical activation on the Ti 2p and O 1s spectra. The presented results are expected to enable the development of more sustainable and effective advanced TiO2-based materials with antimicrobial properties that could be used in numerous green technology applications.

AB  - Luminescence of monoclinic lithium metatitanate (Li2TiO3) powders activated with different quantities of Mn4+ is studied in detail. Its strong deep-red emission arising from the Mn4+ 2Eg → 4A2g spin forbidden transition is centered at around 688 nm and is suitable for luminescence thermometry. Structural and electron paramagnetic resonance analyses show that Mn4+ ions are equally distributed in two almost identical Ti4+ sites in which they are octahedrally coordinated by six oxygen ions. Calculations based on the exchange charge model of the crystal field provided values of Racah parameters (B=760 cm−1, C= 2993 cm−1), crystal-field splitting Dq= 2043 cm−1, and the nephelauxetic parameter β1=0.9775. The maximal quantum efficiency of 24.1% at room temperature is found for 0.126% Mn4+ concentration. Temperature quenching of emission occurs by a cross-over via 4T2 excited state of the Mn4+ ions with T1/2=262 K and is quite favorable for the application in the lifetime-based luminescence thermometry since relative changes in emission decay values are exceptionally-large (around 3.21% at room temperature). We derived theoretical expressions for the temperature dependence of the absolute and relative sensitivities and discuss the influence of host material properties on lifetime sensitivities. © 2019 Wiley-VCH Verlag GmbH & Co.

An original design allowed us to build the apparatus for under 100 $, considerably less than for the commercial equipment. The apparatus must be used with an optical fiber bundle attached to a spectrofluorometer. It is tested for stability and on ZrO 2 :Eu 3+ and Nb 2 O 5 :Eu 3+ samples prepared by a plasma electrolytic process. The tests showed the high stability of the temperature-controlled surfaces. The thermometric properties of the investigated material were tested by the luminescence intensity ratio method of 5 D 1 → 7 F 1 and 5 D 0 → 7 F 2 transitions. The calculated relative sensitivities of Nb 2 O 5 :Eu 3+ and ZrO 2 :Eu 3+ are 3.17% K -1 and 3.07% K -1 at 290 K, respectively, and 0.0012 K -1 at 453 K and 0.000 12 K -1 at 445 K are the calculated absolute sensitivity values, respectively. Nb 2 O 5 :Eu 3+ has shown good thermometric properties up to 180 °C, while ZrO 2 :Eu 3+ is a promising temperature sensor phosphor for higher temperature measurements. © 2019 IOP Publishing Ltd.

AB  - This report focuses on fabrication, characterization, and fundamental optical properties of Eu 3+ - and Sm 3+ -doped GdVO 4 luminescent thin films. Films were uniformly grown on three different substrates: single crystal sapphire (0001), thermally grown silicon oxide (Si/SiO 2 ~ 500 nm) on silicon and fused quartz using pulsed laser deposition technique. Thin films’ structure, morphology, and photoluminescent properties were investigated by X-ray diffraction, atomic force and scanning electron microscopy, diffuse reflectance and photoluminescence spectroscopy. Thin films’ structure characterized by X-ray diffraction showed that for all substrates highly crystalline, zircon-type pure phase films were formed. Films’ thickness and internal morphology were determined by cross-sectional scanning electron microscopy showing completely dense, pore-free film with an average thickness of ~ 390 nm. Atomic force microscopy revealed that the average crystallite size of both Eu 3+ - and Sm 3+ -doped GdVO 4 thin films deposited on fused quartz is higher as compared to the single crystal sapphire (0001) and thermally grown silicon oxide (Si/SiO 2 ~ 500 nm) and that the surface roughness increases with the increase in the grain size. Energy band gap values, estimated from diffuse reflectance spectra were 3.57 and 3.53 eV for Eu 3+ - and Sm 3+ -doped GdVO 4 thin films, respectively. Photoluminescent properties were investigated in detail in both steady state and lifetime domain. The emission spectra show clear orange–red emission in the Sm 3+ -doped GdVO 4 thin films and red emission in Eu 3+ -doped ones. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - Fluorescence excitation-emission matrices were measured for 111 samples of different types of beer and studied by the parallel factor analysis (PARAFAC). The 5-component PARAFAC model was found to suitably describes the beer fluorescence, accounting for 99.4% of the fluorescence variance in the measured set of samples, and providing the completely resolved excitation and emission spectra of each component. The model was chosen based on a model’s core consistency and split-half analysis. It is shown that beer fluorescence is the sum of fluorescence of aromatic amino acids (tryptophan, tyrosine, and phenylalanine), different forms of vitamin B, and phenolic compounds. Obtained PARAFAC model of beer fluorescence demonstrated the potential for the quantification and quality analysis of beer fluorophores and classification of different beer types. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

AB  - An extension of the Judd-Ofelt theory, a theoretical model to the field of Luminescence intensity ratio method in phosphor thermometry has been presented, that enables a calculation of thermometric figures of merit: sensitivity, maximum sensitivity and temperature resolution, by the Judd-Ofelt intensity parameters. The model is applicable for 7 out of 14 lanthanides, and as a testing ground for the model's adequacy, Y2O3 doped with three different Eu3+ concentrations had been chosen. PL spectra were recorded up to 480 °C and photoluminescence and thermometric properties have been obtained. Conventionally estimated thermometric figures of merit have been compared to those obtained by a Judd-Ofelt thermometric model, with a good matching. Consequently, a novel method for calculation of magnetic dipole strength of the mixed induced electric dipole and magnetic dipole transition has been developed. Additionally, an interactive application software has been developed for the quick evaluation of the sensitivity and temperature resolution from Judd-Ofelt intensity parameters. © 2019 Elsevier B.V.

AB  - In this work, the potential of Li1.8Na0.2TiO3:Mn4+ for the lifetime-based luminescence thermometry is assessed. The material is prepared by the solid-state reaction of Li2CO3, Na2CO3, and nanostructured TiO2 at 800 °C, and its monoclinic structure (space group C2/c) is confirmed by X-ray diffraction analysis. In this host, Mn4+ provides strong absorption around 330 nm and 500 nm due to 4A2g → 4T1g and 4A2g→ 4T2g electric dipole forbidden and spin-allowed electron transitions, respectively, and emits around 679 nm on account of 2Eg→ 4A2g spin forbidden electron transition. Temperature dependences of emission intensity and emission decay are measured over the 10–350 K range. Due to the low value of energy of 4T2g level (20000 cm−1), the strong emission quenching starts at low-temperatures which favors the use of this material for the luminescence thermometry. It is demonstrated that the quite large value of relative sensitivity (2.27% K−1@330 K) facilitates temperature measurements with temperature resolution better than 0.15 K, and with the excellent repeatability. © 2019 Elsevier B.V.

AB  - This work explores the influence of annealing temperature on microstructural and optical characteristics of Ce 3+ - doped YPO 4 nanopowders prepared by sol gel method. Samples were annealed at various temperatures (T = 300, 500, 700, 900, 1050 °C), their structure, morphology, and photoluminescent properties were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), TGA-DTA analysis and Photoluminescence spectroscopy (PL). X-ray diffraction analyses confirmed their pure tetragonal zircon structure with average grain size from 5 nm up to 30 nm in dependence on the calcination temperature. The SEM image shows quasi-spherical agglomerated nanoparticles with no heterogenic size. Photoluminescence emission spectra of powders were recorded using excitation wavelength at 245 nm. We investigated the influence of annealing temperature on the optical properties, for samples annealed up to 700 °C no emission has been observed, but the emission increased with annealing temperature above 700° and the characteristic Ce 3+ emission bands (4f 1 →4f 0 5d 1 ) have been observed. Emission intensity increased with annealing temperature due to beter crystallinity and incorporation of Ce 3+ ions in Y 3+ site.

AB  - Defect-fluorite structured Eu 3+ -doped Y 2 Sn 2 O 7 nanoparticles (30–40 nm) were successfully prepared through a facile co-precipitation method without any organic additives or templates followed by calcination in air. Luminescent properties of the as-prepared Y 2-x Eu x Sn 2 O 7 (0.02 ≤ x ≤ 0.6) nanophosphors were fully characterized from an experimental and theoretical point of view (excitation, emission, lifetime, critical concentration, temperature-dependent luminescence and thermal stability, type of interactions and the Judd-Ofelt analysis). The nanophosphors showed relatively sharp excitation bands from 360 to 530 nm and exhibited characteristic emission bands with the most intensive emission centered at 612 nm. In addition, Gd 1.98 Eu 0.02 Sn 2 O 7 and Lu 1.98 Eu 0.02 Sn 2 O 7 samples were prepared in order to study how substitution of RE 3+ (Y 3+ with Gd 3+ and Lu 3+ ions) influences on luminescent properties of RE 1.98 Eu 0.02 Sn 2 O 7 and thermal stability of their luminescence. In order to understand better luminescent properties, the Judd–Ofelt analysis was applied to all the synthesized powders. The highest value of quantum efficiency, ~96%, was estimated for Lu 1.98 Eu 0.02 Sn 2 O 7 .

AB  - EuPO4 and Eu3+-activated REPO4 (RE = La, Dy, Er) ultrasmall fluorescent nanoparticles (NPs) with an average diameter of 2.1 nm were prepared via colloidal synthesis and tested for sensing Cu2+ and other heavy-metal ions. The pure monoclinic monazite crystal structure (space group P121/n1) of the synthesized particles was confirmed using X-ray diffraction measurements, and transmission electron microscopy images showed round particles with a narrow particle-size distribution. The NPs exhibited intense red emission, which is characteristic of the f-f electronic transition of Eu3+, and the quenching of their emission in the presence of heavy-metal ions was revealed by dispersing colloidal particles in a TRIS buffer and then performing photoluminescence measurements. Strong quenching of the emission (at a rate of 0.195 μM−1) was observed upon the addition of Cu2+ ions over the concentration range of 0–10 μM with a limit of detection of 60 nM for Cu2+. The recovery of nearly 90% of the original emission intensity of the probe was achieved via the addition of ethylendiaminetetraacetic acid and was possible in five quenching/recovery cycles. © 2019

AB  - Photoluminescence spectra of bulk YVO4 doped with 1 mol% of Eu3+ and Dy3+ were recorded on the range from room temperature to 733 K, in 20 K steps. The temperature sensing performances were estimated by the luminescence intensity ratio, line-broadening and line-shift methods. The luminescence intensity ratio was tested by the ratio of intensities of 5D1→7F1 and 5D0→7F2,4 transitions of Eu3+, and 4I15/2→6H15/2 and 4F9/2→6H15/2 transitions of Dy3+. The temperature dependent line-broadenings were measured on 5D0→7F2 and 4F9/2→6H13/2 of Eu3+ and Dy3+, respectively. The line-shifts were investigated on 5D0→7F1 and 4F9/2→6H15/2 of Eu3+ and Dy3+, respectively. The experimental data of all three methods is fitted and is in excellent agreement with the theory. The calculated thermometric figures of merit, absolute and relative sensitivities, show the sensor performances at the given temperature, and allow the selection of the best sensor material or transition to be chosen for the desired temperature range. © 2019 Elsevier B.V.

AB  - Judd-Ofelt analysis of HfO2:Eu3+ with various europium doping concentrations, formed by plasma electrolytic oxidation, had been investigated. Ω2 parameter is increasing, while Ω4 parameter shows no concentration dependence. For the highest europium doping concentration of 0.62 at% Ω2 = 4.03·10−20 cm2 and Ω4 = 2.26·10−20 cm2. Radiative transition probabilities of each allowed emitting level were calculated. The radiative lifetime of 5D0 emitting level and a relatively high cross section of emission 5D0→7F2 were estimated: 1.58 ms and 13.49·10−22 cm2, respectively. CIELUV coordinates of photoluminescence of HfO2 doped with various europium concentrations and by excitation with UV 270 nm and 395 nm beam had been calculated and plotted to the CIE 1976 diagram. For low concentrations HfO2:Eu3+ and UV excitation the material gives almost pure white luminescence, which is an indication for its potential use as a white LED phosphor. © 2018 Elsevier B.V.

The first group wasn't dyed, the second group was dyed with natural dye (using sour cherry), and the third one was dyed with artificial aniline dye. For the conservation purposes, all samples were exposed at ambient temperature to gamma radiation doses, from 0.5 to 25 kGy, using a Co-60 irradiator. The influence of gamma irradiation treatment on the color changes was investigated. The obtained results revealed that the irradiation affects the color changes in all samples. All samples became more or less darker under the influence of gamma irradiation. This change in darkness is most pronounced in samples dyed with natural colors.

AB  - One of prospective ways for boosting efficiency of luminescent materials is their combination with noble metal nanoparticles. Collective, so-called plasmon, oscillations of surface electrons in a nanoparticle can resonantly interact with incident or fluorescent light and cause an increase in the light absorption cross section or radiative rate for an adjacent emitter. Plasmonic inorganic phosphors require gentle host crystallization at which added noble nanoparticles will not suffer from aggregation or oxidation. The prospective plasmonic Mg2TiO4:Mn4+ phosphor containing core@shell Ag@SiO2 nanoparticles is prepared here by spare low-temperature annealing of a sol-gel host precursor. It is revealed that Mn4+ luminescence nonmonotonously depends on the size and concentration of 40 and 70 nm silver nanoparticles. It is demonstrated that luminescence of the Mg2TiO4:Mn4+ phosphor can be up to a 1.5 times increase when Mn4+ excitation is supported by localized surface plasmon resonance in Ag@SiO2 nanoparticles. © 2019 American Chemical Society.

It is demonstrated that luminescence of the Mg2TiO4:Mn4+ phosphor can be up to a 1.5 times increase when Mn4+ excitation is supported by localized surface plasmon resonance in Ag@SiO2 nanoparticles. © 2019 American Chemical Society.",

AB  - Single-component white light phosphors with a broad and full color spectrum are urgently required to overcome residual problems with commercial phosphors. In this paper, we describe how Eu3+, as the dopant of Sr3ZnTa2O9 (SZT), plays an important role in structural modulation (including structural order-disorder and intrinsic oxygen defects), as demonstrated by electronic structural calculations and systematic experiments. Furthermore, D-5(0) F-7(2) emission of Eu3+ provides the red component of the emission spectrum and increases the color rendering index of SZT:Eu3+ phosphors. Consequently, the resulting phosphor SZT:10%Eu3+ shows significantly enhanced emission intensity, and its broadband emission covers the entire visible region from 400 nm to 720 nm. A fabricated LED device using a near-ultraviolet 370 nm chip coated with a single-component, the SZT:10%Eu3+ phosphor, shows warm white emission with a high color rendering index (R-a = 82).

AB  - A theoretical model for approximate evaluation of CIE chromaticity coordinates from the Judd-Ofelt intensity parameters has been presented. By reviewing the photoluminescence properties of all the lanthanides, the model's applicability was restricted to Nd3+, Sm3+, Eu3+, Tb3+ and Dy3+. Explicit equations for calculation of CIE coordinates for each of the allowed lanthanides were tested on Y2O3:Eu3+, P2O5·ZnO·Al2O3·BaO·PbO:Tb3+, LiNbO3:Dy3+, LaF3:Sm3+, LaF3:Eu3+, Ca3Sc2Si3O12:Eu3+, and TeO2·TiO2·Nb2O5:Nd3+ by comparing the CIE coordinates of the actual spectra to the coordinates obtained from the Judd-Ofelt parameters, with overall adequate matching. © 2019 Elsevier B.V.

AB  - Background/Aim. Discoloration of dental restorations makes them aesthetically unacceptable and is a frequent reason for replacement of composite restorations. The aim of this study was to evaluate changes of color and fluorescence of resin-based composites (RBCs) exposed to natural juices and energy drinks. Methods. Microhybrid composite Gradia Direct™ Extra Bleach White disc-shaped specimens (n = 35) were immersed in three different natural juices and four different energy drinks. Absorption spectra of natural juices and energy drinks, diffuse reflection and fluorescence of composite samples were measured prior and after seven-day immersion by spectrophotometer Thermo Evolution 600 and spectrofluorometer Fluorolog-3-221. Composite’s color was calculated from diffuse reflection spectra and expressed in CIELAB color space (Commission International de l’Eclairage). Results. All natural juices and energy drinks induced color change of resin based composites, but to the different extent. Only aronia and carrot juices induced total color change considerably higher than clinically acceptable threshold, 9.3 and 6.2, respectively. All energy drinks and aronia juice induced notable decrease in fluorescence; the highest change of 28% was evidenced in the case of aronia juice. Conclusion. Change of color and fluorescence will appear differently with various solutions due to different chemical composition and concentration of colorant species in different beverages. Solutions with higher optical absorption induced higher total color change. Discoloration of composites in aronia and carrot juices is similar to those earlier reported for red wine, tea and coffee. © 2018, Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.
