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 Zn_2P electron and the lower kinetic energy of the Auger Zn L₃ M_{4, 5} M_{4, 5} electron, as well as the lower binding energy of the Si_2P electron, which implies the participation of Zn^{2 +} cations in the glass network to form the Zn-O-Si bond.
