Radiation effects, photoluminescence and radioluminescence of Eu-doped (Y0.7Gd0.3)2O3 nanoparticles with various sizes
(Optical Materials, 2018)
(Y1-xLnx)2O3 oxides (Ln = Y, Gd, Lu) doped with Eu3+ ions are widely used as commercialized scintillators in medical and industrial scanning applications, with high performance and attractive properties. In this work, ...
Annealing effect on the photoluminescence properties of Ce3+ doped YPO4 nanophosphors
(Optical Materials, 2019)
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 = ...
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 ...
The enhancement of emission intensity and enlargement of color gamut by a simple local structure substitution with highly thermal stability preserved
(Optical Materials, 2019)
The local crystal structure engineering becomes an important strategy to design new phosphors with enhanced optical and thermal performance of white light-emitting diodes. Herein, a series of Na3Sc2(PO4)3: Eu2+ and ...
About the nature of luminescent bands in undoped and Eu2+ doped SrAl2O4 phosphors
(Optical Materials, 2023)
In this paper we report the luminescence properties of nanosized undoped and Eu2+ (1%) doped SrAl2O4 phosphors. The samples were prepared by combustion method at 600 ◦C followed by annealing of the resultant combustion ash ...
Optical properties and fluorescence of quantum dots CdSe/ZnS-PMMA composite films with interface modifications
(Optical Materials, 2019)
Processing and characterization of polymer nanocomposites based on poly (methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots (QD's) were presented in this work. The aim is to preserve the ...
