Optical absorption and infrared spectroscopic analysis of γ-irradiated ZnO–BaO–B2O3 glasses

A new series of borate glasses containing ZnO and BaO as network modifiers with compositions of xZnO–2xBaO–(1 − 3x)B2O3 (x varying from 0.10 to 0.21 mol fraction) were prepared by conventional melt quenching. Optical and structural properties were determined before and after successive γ-ray irradiation at 2.5 kGy dose using, UV–vis and Fourier transform infrared spectroscopic techniques to elucidate the effect of γ-irradiation. The results are supported by additional density and molar volume studies.
