Abstract
- Photoluminescence (PL) of Gd-doped silica in the ultraviolet (UV) is investigated. The strong emission detected at 314 nm is assigned to the 6P7/2 to 8S7/2 transition under excitation of 6DJ, 6IJ, and 6PJ energy levels of the Gd3+. After glass densified by rapid thermal treatment (RTT), significant enhanced luminescence and decreased loss covering the UV band are observed.
