Abstract
The influence of -ray irradiation on the optical properties of glass has been investigated. Broadband infrared (IR) emission at 1310 nm with a FWHM over 200 nm is observed in the -ray irradiated glass. The IR luminescence depends on the -ray irradiation dose and the concentration of . The thermal stability of the -ray irradiated IR luminescence center is studied, and the origin of the IR luminescence center has been suggested.
