Novel method of phosphorescent strontium aluminate coating preparation on aluminum
(Elsevier Ltd, 2018)
This study presents a novel approach to produce phosphorescent coatings on metal surfaces. Strontium aluminates are the most popular modern phosphorescent materials exhibiting long afterglow at room temperature and a broad ...
X-ray excited luminescence of SrAl2O4:Eu,Dy at low temperatures
(Elsevier B.V., 2018)
Particle size effects on the structure and emission of Eu3+:LaPO4 and EuPO4 phosphors
(Elsevier B.V., 2018)
This paper provides the detailed study of (nano)particle's size effect on structural and luminescent properties of LaPO4:Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
High resolution luminescence spectroscopy and thermoluminescence of different size LaPO4:Eu3+ nanoparticles
(Elsevier B.V., 2018)
Nanoparticles (5 nm) and nanorods (2 nm × 15 nm and 4 nm × 20 nm) of monoclinic monazite LaPO4:Eu3+ were prepared by reverse micelle and co-precipitation techniques. Effects of the particle size and surface defects on the ...
Solvothermal synthesis derived Co-Ga codoped ZnO diluted magnetic degenerated semiconductor nanocrystals
(Elsevier Ltd, 2018)
Here we are reporting solvothermal synthesis derived diluted magnetic and plasmonic Co-Ga co-doped ZnO nanocrystals with high magnetization values (from 1.02 to 4.88 emu/g) at room temperature. Co-Ga co-doped ZnO nanocrystals ...
Synthesis, structure and spectroscopic properties of luminescent GdVO4:Dy3+ and DyVO4 particles
(Elsevier B.V., 2018)
In this work, we focused on the syntheses, structure and spectroscopic properties of GdVO4:Dy3+ and DyVO4 (nano)particles of different sizes and shapes (spherical nanoparticles of 2 nm, 4 nm, and 20 nm in size, nanorods ...
Reversible Photodoping of TiO2 Nanoparticles for Photochromic Applications
(American Chemical Society, 2018)
Observations on the strong photochromic effect of crystalline TiO2 quantum dots (mean size ≈ 4 nm) are presented. The synthesized quantum dots consist of irregularly shaped anatase TiO2 nanoparticles (NPs) and are dispersed ...
Niobium enhanced europium ion luminescence in hafnia nanocrystals
(Elsevier B.V., 2018)
In this work we demonstrate a method where by adding Nb ions, Ln3+ ion luminescence intensity in HfO2 is increased for up to 15 times (in a sample containing 5 mol%Eu). The effect is described as niobium acting as a charge ...
Magnetron sputtering fabrication of α-Al2O3:Cr powders and their T thermoluminescence properties
(Elsevier B.V., 2018)
For many years doped α-Al2O3 has attracted interest as a dosimeter for personal, environment monitoring and food control. The alumina single crystal growth is a difficult process; however, materials in form of powders, ...
Up-conversion luminescence of GdVO4:Nd3+/Er3+ and GdVO4:Nd3+/Ho3+ T phosphors under 808 nm excitation
(Elsevier B.V., 2018)
In recent years, there exists a tendency in research of up-conversion materials to shift excitation from 980 nm to shorter wavelengths. Here, in order to produce up-conversion luminescence emission of GdVO4-based materials ...
