The effect of radiation on the optical properties of glasses is very important as the response of the glasses to radiation is related to the rate of formation and accumulation of induced defects during progressive irradiation and hence the production of characteristic color center. In the present book, the effect of glass composition and gamma irradiation on the optical and physical properties of some selected borate and borosilicate oxide glasses have been explained. These glasses have potential application in the field of electronics, nuclear and solar energy technologies, acoustic-optic...
