PSHB has been observed at room temperature in Sm-doped crystals and glasses. Among them, glasses are considered to be more favorable than single crystals, due to their wide inhomogeneous line width and easy process for mass production. In the study, we developed a new glass mixture which shows room temperature PSHB with a inhomogeneous line width broadened up to 70 cm-1. The PSHB was characterized by investigating the time decay pattern of fluorescence and the excitation spectra. ？ 1999 IEEE. English Institute of Electrical and Electronics Engineers Inc.
