摘　　要：通过对柠檬酸盐分解法的改进,在800℃的低温下合成了YAG:Ce立方晶荧光粉体,用X-射线衍射法研究了YAG的成相过程。结果表明:Y2O3与Al2O3的摩尔比为3.3:5时更易形成YAG相,成相过程是由无定型态直接转变为YAG相的。同时考察了样品的发光性质。Single-phase cubic YAG：Ce crystalline nanosized phosphor has been successfully synthesized via the improved citrate decomposition method at temperature as low as 800℃.The formation process of Y3Al5O12 phase was investigated.The results indicate that YAG phase would be formed easier when mole ratio of Y2O3：Al2O3 is 3.3：5.Meanwhile,the photoluminescence properties of YAG：Ce were investigated.
