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 L₃M_4,5M_4,5 electron, as well as the lower binding energy of the Si_2P electron, which implies the participation of Zn²⁺ cat ions in the glass network to form the Zn–O–Si bond
