title: Broadband infrared luminescence in γ-ray irradiated bismuth borosilicate glasses.
abstract: The influence of γ-ray irradiation on the optical properties of Bi(2)O(3)-B(2)O(3)-SiO(2) glass has been investigated. Broadband infrared (IR) emission at 1310 nm with a FWHM over 200 nm is observed in the γ-ray irradiated glass. The IR luminescence depends on the γ-ray irradiation dose and the concentration of Bi(2)O(3). The thermal stability of the γ-ray irradiated IR luminescence center is studied, and the origin of the IR luminescence center has been suggested.
