AB  - Mn2+ single doped as well as Mn2+/Eu2+ and Mn2+/Ce3+ co-doped Al2O3 coatings were synthesized by plasma electrolytic oxidation process of aluminum and their structural, morphological, and above all, photoluminescence (PL) properties were investigated in deep. Al2O3:Mn2+ coatings exhibit a weak green PL emission centered at about 525 nm attributed to 4T1 → 6A1 forbidden transition of Mn2+. Under middle UV excitation, Eu2+ or Ce3+ single doped Al2O3 coatings show strong and broad PL emission mostly in range from 300 to 550 nm. Due to the overlap between the PL emission of Eu2+ or Ce3+ and the PL excitation of Mn2+ in Al2O3, efficient Eu2+  → Mn2+ and Ce3+  → Mn2+ energy transfer upon middle UV excitation was observed in Al2O3:Mn2+/Eu2+ and Al2O3:Mn2+/Ce3+, respectively. PL emission intensities of Mn2+ in Al2O3:Mn2+/Eu2+ and Al2O3:Mn2+/Ce3+ is two to three orders of magnitude larger than in Al2O3:Mn2+.

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  - 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  - In this paper, Dy3+ and Dy3+/Ce3+ doped Al2O3 coatings were synthesized by plasma electrolytic oxidation process of aluminum. Structural and photoluminescence (PL) properties of obtained coatings as well as energy transfer mechanism from Ce3+ to Dy3+ were studied. The PL excitation and emission spectra of Al2O3:Dy3+ featured weak bands attributed to f-f transitions of Dy3+. The PL emission spectrum of Al2O3:Dy3+ exhibits three emission bands in blue-yellow-red regions, assigned to F-4(9/2)-> H-6(15/2), F-4(9/2)-> H-6(13/2), and F-4(9/2)-> H-6(11/2) transitions of Dy3+, respectively. Under middle UV excitation the Ce3+ in Al2O3 emits broad band, peaked at about 330 nm, attributed to the 5d -> 4f transition of Ce3+. Because of the strong overlap between the PL emission of Ce3+ and the PL excitation of Dy3+ in Al2O3, energy transfer from Ce3+ to the Dy3+ in Al2O3:Dy3+/Ce3+ is observed upon 285 nm excitation. PL emissions due to F-4(9/2)-> H-6(J) (J = 11/2, 13/2, and 15/2) transitions of Dy3+ in Al2O3:Dy3+/Ce3+ is two to three orders of magnitude larger than in Al2O3:Dy3+. The values of CIE chromaticity coordinates for Al2O3:Dy3+/Ce3+ suggest their application for cold white light emission.

AB  - The steady-state luminescence thermometry analysis was performed on thin-films of undoped Gd2O3 and Gd2O3 doped with Ho3+, Eu3+ and Er3+, created by the plasma electrolytic oxidation process. The experimental setup for luminescent measurements closely resembles the practical luminescent fiber-optic thermometer. The visible PL from Gd3+ was utilized for the luminescence intensity ratio method, exceling over the traditional method by using the thermally coupled levels, as it is superior by either better sensitivities, widened temperature range or improved temperature resolution. The relative uncertainty by our method is ~300 times lower @ 300 K for Gd2O3:Eu3+. The maximum relative sensitivities by the luminescence intensity ratio (LIR) of Gd2O3:Ho3+, Gd2O3:Eu3+ and Gd2O3:Er3+ are 0.12% @ 295 K, 0.44% @ 580 K and 1.1% @ 290 K, respectively. Line-shift showed a significant change solely for Eu3+ doped sample, by 0.076 cm−1 K−1. The full-width-half-maximum (FWHM) changes of undoped Gd2O3 and doped by Eu3+ at the high rate of 0.3 cm−1 K−1 @ 573 K and 0.53 cm−1 K−1 @ 300 K, respectively, but was marked impractical for other samples.

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.

AB  - A complete apparatus for luminescence thermometry has been built comprising a programmable hot-plate up to 400 °C, a hot/cold plate 0 °C-80 °C, a control circuit with thermocouple feedback, a platinum resistance thermometer and an oven for calibration. 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  - 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.

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  - TiO2/WO3 composites supported on a stainless steel foil were prepared by the spray pyrolysis technique. Content of WO3 was gradually increased from 1 wt% to 100 wt.%, while the coating thickness was limited to about 1 pm. The coatings were characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. The photocatalytic activity of obtained coatings was investigated by degradation of methyl orange, used as model pollutant. The results show that with increasing WO3 content up to 10 wt.% photoactivity increases as result of better charge separation that could effectively prevent the recombination of photogenerated electrons and holes. Further increase of WO3 content led to decrease of photoactivity. (C) 2014 Elsevier B.V. All rights reserved.

Further increase of WO3 content led to decrease of photoactivity. (C) 2014 Elsevier B.V. All rights reserved.",
