It was known that photoluminescence phenomenon was observed in Mn2+-doped SiO2-B2O3-ZnO glass after the irradiation of ultraviolet light at room temperature, and there was the shift of the spectra after heat treatment at 700 oC for crystallization. In this study, we report the effect of sintering on photoluminescence. The main emission wavelength of all samples was in a range from 520 nm to 541 nm which was different with 560 nm of ceramic produced after heat treatment for crystallization. This was measured by photoluminescence spectrometer and the change of the fluorescence was due to the alteration of crystal structure of Mn2+. The crystalline phase was analyzed as Zn5B4O11.
