Abstract

ZnO based silicate glasses are presented in the present paper. Irradiation resistance of glass samples is tested under the gamma-ray radiation at the doses of 71 and 262 Gy. Ultraviolet and visible transmitting spectra of glass samples are compared before and after irradiation treatment. Test results show that irradiation damage on ZnO containing glasses increases with dose while the glass with the Al₂O₃ donor dopants exhibits much improved irradiation resistance. The latter can be correlated to band-gap broadening effect due to Al₂O₃ doping in the ZnO containing glass and to the role of Al³⁺ as the network intermediate to enter partially the tetrahedral structure of silicate glass.
