摘要：
Tb3+/Yb3+ co-doped precursor glass was synthesized by melt quenching method, and transparent glassceramic was prepared by heat treatment the precursor glass. Comparing the X-ray diffraction patterns of precursor glass and glass-ceramic showed that the Na3.6Y1.8(PO4)(3) crystals were formed after heat treatment. By the scanning electron microscopy images of glass-ceramic, the grainy crystal grains were observed dispersed in the glass matrix. The structure of precursor glass and glass-ceramic was studied by FTIR spectra and Raman spectra, indicating that phosphate group was formed in glass-ceramic. The up-conversion luminescent intensity of glass-ceramic was obviously enhanced than precursor glass. Moreover, the luminescence quantum yield of the glass-ceramic sample showed higher than precursor glass, which can be attributed to the formation of phosphate groups in glass-ceramic.
