Abstract
ZnO-SiO2-BaO(BaF2) glasses are studied in the search for a novel scintillating material. Photoluminescence of such glasses was measured within 8-300 K including the decay kinetics and also the XPS spectra were obtained on selected samples to have information about Zn-O-Si bonding in the glass. Glass emission occurs in the violet-blue spectral range and decay kinetics is governed by the decay times of hundreds ns - units μs. XPS measurements reveal the higher binding energy of the Zn2P electron and the lower kinetic energy of the Auger Zn L3 M4, 5 M4, 5 electron, as well as the lower binding energy of the Si2P electron, which implies the participation of Zn2 + cations in the glass network to form the Zn-O-Si bond.
