摘　　要：用Na_2O-Li_2O-Al_2O_3-B_2O_3-SiO_2硼硅酸盐体系的低熔点玻璃作为基质玻璃,采用两步熔融法制备了Ce:YAG荧光玻璃.利用SEM,EDS和荧光光谱仪对样品进行了显微结构和光学性能分析.实验结果表明:样品由玻璃基质和Ce:YAG晶粒组成,晶粒均匀地分散在硼硅酸盐玻璃基质中;样品在340和460nm处有两个激发峰,发射光谱在533nm处有一宽峰,属于Ce^(3+)的5d→4f特征跃迁发射.Ce:YAG荧光玻璃是一种可用于白光LED的新型荧光材料.The Ce： YAG glass phosphor based on Na2O-Li2O-Al2O3-B2O3-SiO2 borosilicate glass was prepared by two-step melting methods,and it were characterized by scanning electron microscope （SEM）, energy dispersive spectrometer （EDS） and fluorescence spectrometer, respectively. The results show that the Ce：YAG glass phosphor is composed of glass and Ce：YAG,and the Ce：YAG phase dispersed well in the matrix of glass. The excitation spectra had a weak band at 340nm and a strong band at 460 nm. The broad emission peaks at about 533 nm is attributed to 5d→4f transition of Ce^3＋ ions. All results show that Ce：YAG glass phosphors may be a promising fluorescent material for white LED applications.
