Effects of Humidity, Temperature and Time on the Nd:YAG Nano-powders during the Aging Process

doi:10.3724/SP.J.1077.2011.01273

Abstract

Abstract: 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.

Key words: Nd:YAG, nano-powders, humidity, aging
