采用微波辅助均相沉淀法制备了Nd:YAG(Nd:Y3Al5O12)纳米粉体. 通过XRD和SEM对此方法制备的Nd:YAG纳米粉体进行了分析表征, 并分析了在陈化过程中, 湿度、温度和陈化时间对制备Nd:YAG纳米粉体的影响. 实验结果表明: 陈化环境的湿度、温度和陈化时间对制备Nd:YAG纳米粉体的组分和形貌有显著的影响. 陈化环境中湿度和温度对Nd:YAG纳米粉体的影响具有一定的依存关系, 必须适当地控制; 陈化时间对Nd:YAG纳米粉体的粒径大小影响显著, 随着陈化时间的延长, 获得的Nd:YAG纳米粉体的颗粒尺寸先减小后增大.
The Nd:YAG (Nd:Y3Al5O12) nano-powders were successfully prepared by the microwave-assisted homogeneous precipitation method. The Nd:YAG nano-powders were analyzed by means of XRD and SEM. The effects of humidity, temperature and aging time during the aging process on the preparation of the Nd:YAG nano-powders were discussed. The results show that the composition and morphology of the Nd:YAG precursors and Nd:YAG nano-powders are remarkably affected by the above factors. Effects of environmental humidity and temperature on the preparation of the Nd:YAG nano-powders are dependent on each other, which must be properly controlled. And the aging time can significantly affect sizes of the Nd:YAG nano-powders. Particle size of the Nd:YAG nano-powder decreases and then increases with the aging time increasing.
