Sol-gel glass nanocomposite scintillator

ORAL

Abstract

Nanocomposite LaBr$_{3}$:Ce$^{3+}$ and SiO$_{2}$ are prepared by using sol-gel method. Concentration of LaBr$_{3}$:Ce$^{3+}$ embedded in SiO$_{2}$ can be as high as 95{\%}. But the sol-gel glass only is transparent up to a concentration of 50{\%}. Emission and excitation spectra are measured. Ce3+ emission is strong and is found at near UV region. This sol-gel nanocomposite material is good for scintillators application.
