摘要：
The density, molar volume, optical energy bandgap, and infrared absorption spectra in the range 400-4000 nm of borate glasses with composition 2xLi(2)O-xAl(2)O(3)-(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 gamma-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 gamma-ray and the changes in optical properties have been discussed.
