Microstructure and Luminescent Properties of the YAG: Ce Phosphor-Doped Glass of the P<sub>2</sub>O<sub>5</sub>-ZnO-SiO<sub>2</sub> System

Abstract

Lminescent glass is widely used in building, energy saving, emergency lighting and art crafts; The energy consumption for global illumination is rising year by year, and the energy consumption has become a global problem; the research of luminescent glass is important for the developing of the energy-saving light. In this paper, the glass of the P2O5-ZnO-SiO2 system was used as matrix material, the matrix material was doped with yttrium aluminum garnet crystals containing Ce (YAG:Ce phosphors) and then were sintered for the preparation of the luminescent glass. Using X-ray diffraction and fluorescence spectrometer, the effects of the doping quantity, sintering temperature and sintering time on luminescent properties were studied. The results show that, for the P2O5-ZnO-SiO2 glass, excitation at 340 nm and 468 nm, produced emission at 544 nm; Doping quantity, sintering temperature and sintering time affect intensity of emission peak, but do not affect the position of emission peak.
