摘　　要：以柠檬酸为燃料,采用低温燃烧法制备了Nd∶YGG纳米粉体,利用XRD、红外光谱、SEM及荧光光谱等测试方法对粉体的结构、形貌及荧光性能进行了表征。结果表明,煅烧温度为900℃时粉体已形成Nd∶YGG纯相;Nd∶YGG粉体平均粒径约为30 nm;粉体的最强荧光发射峰位于1064.94 nm,是Nd3+的4F3/2→4I11/2能级跃迁导致的荧光发射。Nd∶YGG nanopowders were prepared by low temperature combustion method using citric acid as fuel.The structure and fluorescence properties of Nd∶YGG powders were characterized by XRD,IR,SEM and fluorescence spectrum.The results indicated that the Nd∶YGG pure phase is formed when it is calcined at 900 ℃,the size of Nd∶YGG powders are about 30 nm.The fluorescence spectrum indicate that the strongest emission peak of the Nd∶YGG powders is 1064.94 nm,which result from the energy transition of 4F3/2→4I11/2 of Nd3＋.
