摘　　要：以尿素作燃料采用快速燃烧法,得到了YAG:Tb材料的前驱粉末.对前驱粉末热处理后,合成了YAG:Tb荧光材料.通过XRD、SEM和PL光谱等技术,测定了该材料的结构、形貌及发光特性.虽然制备过程中没有加入助熔剂,但该材料的化学纯度明显得到提高.YAG:Tb荧光粉的颗粒精细、分布均匀,粒径在1-2μm之间.分析了YAG:Tb和YAG:Ce,Tb的发光特性.By applying combustion process with urea as the fuel, the precursor powders of the phosphor were obtained. After the heat treatment to the precursor powders, YAG:Tb phosphor was synthesized. The characteristics of the phosphor were determined by XRD, SEM and PL spectra techniques. The chemical purity of the phosphor was greatly improved though no flux added to the phosphor. The particle sizes of the phosphor were fine (1similar to2mum) and well-distributed. The luminescent properties of YAG:Tb and YAG:Ce,Tb were analyzed.
