The changes in Raman spectra of alkali borate glasses with and without Al2O3under high dose of gamma irradiation have been reported. Glasses with composition xK2O.yAl2O3.(1-x-y)B2O3(x = 20 or 30 mol%; y = 0, 10 or 15 mol%), have been prepared by melt-quenching technique. In order to investigate the role of Al2O3in the network of potassium borate glasses, aluminium oxide has been added at the expense of B2O3keeping the amount of alkali same. Gamma irradiation has been performed at a dose rate of 573 Gy.h-1with total absorbed dose of 50 KGy. Samples were characterized before and immediately after irradiation by Raman spectrophotometer. The experimental results clearly indicate a significant change in the structure of borate glass matrix after irradiation, and the dependence of irradiation effects on composition of alkali as well as on aluminium oxide content. © 2012 Copyright The Indian Ceramic Society.
