Abstract

This research paper reports about the change in optical spectra of alkali aluminoborate glasses under high dose of gamma irradiation. Effect of irradiation on visible spectra finds remarkable applications in optoelectronic materials. Glasses with a host matrix composed of M2O (where M=Na, K),Al2O3,B2O3 were prepared by conventional melt quench technique. Gamma irradiation was performed at a dose-rate of 573 Gy/h to a total dose of 50 kGy. Samples were characterised before and immediately after irradiation by UVvis transmission spectra in the range of 200800 nm. The induced absorption coefficient and loss of transmission due to irradiation were attributed to the nature of alkali metals as well as the host matrix. © 2012 Elsevier B.V. All rights reserved.
