Optical and structural properties of Li2O–Al2O3–B2O3 glasses before and after γ-irradiation effects

The density, molar volume, optical energy bandgap, and infrared absorption spectra in the range 400–4000 nm of borate glasses with composition 2xLi2O–xAl2O3–(1–3x)B2O3 (x varying from 0.10 to 0.18 mol fraction) prepared by conventional melt quench technique have been measured before and after successive γ-ray irradiation at the dose of 2.5 K Gy to elucidate the effect of gamma irradiation on such glasses. The radiation induced defects created by γ-ray and the changes in optical properties have been discussed.
