Preparation of GaN Powder and the Theoretical Calculation of Optical Properties

摘要：

In this paper, the sol-gel method is used to prepare the nano GaN powder, we use Ga2O3 as gallium source, NH3 as nitrogen source, citric acid as the chelating agent to prepare the former drive material, after to be jello, and we put it into NH3 environment to get the nano GaN sample. When CA:Ga=l:l, PH value is 7, pretreatment temperature is 400X2, annealing temperature is 950℃, we can get the GaN powder material which has good quality and crystallinity. The photoluminesc- ence peaks by PL spectrum show that GaN has good optical performance, through the first principle calculation we know that the optical performance parameters fit well with the experimental value.
