| 摘 要： | 采用碳酸盐共沉淀法制备掺钕钇铝石榴石纳米粉体,利用XRD、SEM和荧光光谱等测试手段分析了钕钇铝石榴石纳米粉体的物相结构和光谱特性。结果表明:在1100℃和pH=7时,合成质量较好的YAG纳米粉体,颗径尺寸大约为80nm。在508cm~(-1)、566cm~(-1)、690cm~(-1)、720cm~(-1)、785cm~(-1)附近的一系列吸收峰均为YAG中晶格振动与光子相互作用所引起的,在808nm激发下获得了最佳掺杂浓度。

| Abstract: | Neodymium doped yttrium aluminum garnet nano powders were prepared by the co-precipitation method. The phase structure and spectral properties were investigated by means of X–ray diffraction,scanning electron micros-copy and fluorescence spectrum, etc. The results indicate that the YAG nano powders with good quality were at the temperature of 1100℃ and pH value of 7, and the particle size is about 80nm. The peaks at around 508cm-1、566cm-1、690cm-1、720cm-1、785cm-1 can be assigned to the interaction of the photons and lattice vibration in YAG, the optimum doping concentration was obtained under 808nm excitation. |
