Tb3+ doped NaF-Y2 O3-Al2 O3-SiO2 glass was synthesized by melting method,and YAG glass-ceramic was obtained after heat treating at different temperatures. The YAG crystal phase, morphology, and luminescence properties were examined by X-ray diffraction ( XRD ) , scanning electron microscopy ( SEM) and photoluminescence spectroscopy. The results showed that the pure YAG phase could be obtained after heat treating at 1 300℃,and the grain size of the Tb:YAG phase was between 25~75 nm. The green emission intensity of Tb3+ in the glass ceramic was enhanced,and the blue emission intensity of Tb3+ was decreased.
