Density, UV-VIS transmission spectra and fluorescence spectrum of the glasses were investigated. SrO-ZnO-B O -SiO (SZBS) glass has high transmission capability in visible light region. The excitation peak of SZBS 2 3 2 glass locates around 221 nm. The photoluminescence spectrum of SZBS glass is a broad band with peaks around 410, 475 and 502 nm, which are attributed to the exciton emission of ZnO, interspaceal Zn atoms recombination luminescence, electron and deep captured hole recombination process, respectively. Besides the excitation peak appears red-shift, the transmission ratio of glasses improves and
