Abstract :
Summary form only given. There are several reports of visible luminescence from bismuth-doped glasses and crystals. The spectra of these crystalline and glassy materials were very wide, and the absorption and the fluorescence peaks exist around 240 nm and 380 nm, respectively, however, these emissions from Bi/sup 3+/ are no use for optical communication. We found a new infrared emission at 1.25 /spl mu/m from the bismuth doped silica glass. We report a new infrared fluorescence of bismuth-doped silica glass.
