摘　　要：分别采用高温固相法和湿化学方法(以NH4HCO3为沉淀剂的共沉淀法,以乙二胺为溶剂的溶剂热法以及以柠檬酸为螯合剂的溶胶-凝胶法)制得YAG:Ce3+黄色荧光粉,对在不同条件下所得的YAG:Ce3+黄色荧光粉的相态、结晶度、发光性能等特性进行了深入的研究,从而得出各合成方法中最适宜的煅烧温度、Ce3+掺杂量、滴加速度等因素对所得荧光粉的晶化过程、发光性能的影响规律,以便更好地改善YAG:Ce3+黄色荧光粉并推动其进一步的市场化应用。Yellow phosphor YAG： Ce3＋ was synthesized by different methods： solid-state method, co-precipitation with ammonium hydrogen carbonate, solvothermal with ethylenediamine and sol-gel with citric acid. The morphologies, crystallization and luminescent properties of the phosphors prepared by different methods were studied in order to find the best factors of sintering temperature,Ce ion concentration, the speed of dropping mother salts into NH4 HCO3 solution and so on. Then we can promote phosphor YAG：Ce3＋ into our daily life.
