Lanthanide-doped orthovanadate phosphors: Syntheses, structures, and photoluminescence properties
(Woodhead Publishing, 2020)
A comprehensive systematic review is given of developments, trends, and advances over the past two decades in research on orthovanadates of monovalent, divalent, and trivalent metals, MI3VO4, MII3(VO4)2, and MIIIVO4, ...
Highly-increased photoluminescence of Pr3+ due to the Eu2+→ Pr3+ energy transfer in Al2O3 coatings formed by plasma electrolytic oxidation
(Journal of Luminescence, 2020)
In this paper, photoluminescence (PL) properties of Pr3+ single doped and Pr3+/Eu2+ co-doped Al2O3 coatings formed by plasma electrolytic oxidation of aluminum were investigated. The PL spectra of Al2O3:Pr3+ coatings feature ...
Temperature and concentration dependent Judd-Ofelt analysis of Y2O3:Eu3+ and YVO4:Eu3+
(Physica B: Condensed Matter, 2020)
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 ...
Dy3+ and Dy3+/Ce3+ doped Al2O3 coatings obtained by plasma electrolytic oxidation: Photoluminescence and energy transfer from Ce3+ to Dy3+
(Journal of Luminescence, 2020)
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 ...
Photoluminescence of ZnO:Eu3+ and ZnO:Tb3+ coatings formed by plasma electrolytic oxidation of pure zinc substrate
(Journal of Luminescence, 2021)
Eu3+ and Tb3+ doped ZnO optical coatings were formed by the Plasma Electrolytic Oxidation (PEO) method from the pure Zn sheet, with various dopant concentrations. The morphologies show no significant change with the ...
La2O2S:Er3+/Yb3+ nanoparticles synthesized by the optimized furnace combustion technique and their high-resolution temperature sensing
(Optik, 2021)
Nanoparticles of less than 100 nm of La2O2S co-doped with Er3+ and Yb3+ in 2% and 12% concentrations, respectively, were synthesized by the improved furnace combustion technique that limits the precursor usage and without ...
Zinc oxide nanoparticles prepared by thermal decomposition of zinc benzenepolycarboxylato precursors: Photoluminescent, photocatalytic and antimicrobial properties
(Journal of the Serbian Chemical Society, 2020)
Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal ...
Judd-Ofelt parametrization from emission spectra: The case study of the Eu3+ 5D1 emitting level
(Chemical Physics, 2020)
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 ...
Photoactive and antioxidant nanochitosan dots/biocellulose hydrogels for wound healing treatment
(Materials Science and Engineering: C, 2021)
Bacterial infection and their resistance to known antibiotics delays wound healing. In this study, nanochitosan dots (nChiD) produced by gamma irradiation have been encapsulated in bacterial cellulose (BC) polymer matrix ...
A facile self-passivation strategy for improving moisture-resistance of fluoride red phosphors without surface modification
(Optical Materials, 2021)
Mn4+-activated fluorides rank among the most significant red phosphors for white light emitting diodes (LEDs) with enhanced color rendition, while their poor moisture resistance hinders further application. Surface coating ...
