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 ...
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 ...
Radioluminescence, thermoluminescence and dosimetric properties of ZnO ceramics
(Elsevier Ltd, 2017)
Two types of ZnO ceramics were fabricated and characterized by XRD, SEM methods. The radioluminescence spectra were measured within the 300–550 K range. The defect luminescence band peaking at ~2.35 eV is the dominant one ...
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, ...
Excitation Transfer Engineering in Ce-Doped Oxide Crystalline Scintillators by Codoping with Alkali-Earth Ions
(Wiley-VCH Verlag, 2018)
Time-resolved spectroscopic study of the photoluminescence response to femtosecond pulse excitation and free carrier absorption at different wavelengths, thermally stimulated luminescence measurements and investigation of ...
Nanoengineered Gd3Al2Ga3O12 Scintillation Materials with Disordered Garnet Structure for Novel Detectors of Ionizing Radiation
(Wiley-VCH Verlag, 2019)
The search for engineering approaches to improve the scintillation properties of Gd3Al2Ga3O12 crystals and enable their production technology is of current interest. This crystal, while doped with Ce, is considered a good ...
Behaviour of advanced tritium breeder pebbles under simultaneous action of accelerated electrons and high temperature
(Elsevier Ltd, 2017)
Advanced lithium orthosilicate (Li4SiO4) pebbles with additions of lithium metatitanate (Li2TiO3) as a secondary phase are suggested as a potential source for tritium breeding in future nuclear fusion reactors. The advanced ...
Synthesis of Eu2+ and Dy3+ doped strontium aluminates and their properties
(Trans Tech Publications Ltd., 2017)
Strontium aluminate phosphors were synthesized by the solution combustion method using citric acid, urea or glycine as reducing agent and europium and dysprosium as dopants. The content of both dopants was in the range of ...
Sub-nanosecond excitonic luminescence in ZnO:In nanocrystals
(Elsevier Ltd, 2019)
The effects of indium concentration influence on the morphology, luminescence spectra and luminescence decay kinetics of ZnO:In nanocrystals prepared by the solar physical vapour deposition method are investigated. While ...
The boron effect on low temperature luminescence of SrAl2O4:Eu, Dy
(Elsevier Ltd, 2020)
Temperature dependence of the afterglow of persistent luminescence material SrAl2O4:Eu,Dy is a major problem for outdoor low temperature applications. Therefore this publication deals with tailoring the material for better ...
