The preparation and luminescence of Sm2O3 doped glass ceramics containing Na3Y(PO4)2

Abstract

Sm2O3 doped transparent glass ceramics containing Na3Y(PO4)2 crystal phase were synthesized by melting crystallization method. The structure and morphology of the glass ceramics were characterized with X-ray diffraction (XRD) and scanning electron microscopy (SEM). The heat treatment condition of Sm2O3 doped Na3Y(PO4)2 crystal phase glass was 660°C/2h. The glass ceramics with Sm2O3 doped Na3Y(PO4)2 phase are excited by 403nm, and there are emission peaks at 564nm, 600nm and 648nm, respectively. The emission peak intensity of 600nm is the largest, which produces orange light, corresponding to the 6G5/2→4H7/2 transition of Sm3+. Excitation and emission spectra show that the fluorescence intensity was the highest when the concentration of Sm2O3 was 0.6mol%, and the fluorescence lifetime was 2.9377ms.
