氮化镓粉末的溶胶凝胶法制备及其结构
摘要:
报道了一种新颖而有效的二步制备氮化镓粉末的方法. 以乙氧基镓Ga(OC2H5)3作前驱体, 利用溶胶-凝胶法和高温氨化法相结合, 在950 ℃氨化温度下, 将凝胶与流动的NH3反应20 min, 合成了GaN粉末. XRD、FTIR、TEM及SAED的测量结果表明, GaN粉末是六方纤锌矿结构的单晶晶粒, 粉末粒度较均匀, FTIR吸收谱有明显的宽化现象.

Structure and Synthesis of GaN Powder by Sol-Gel Method
Abstract:
A novel and efficient method was applied to prepare gallium nitride (GaN) powder. Hexa nal gallium nitride (GaN) powder was successfully synthesized by means of a combination of sol-gel process with high temperature ammoniation using Ga(OC2H5)3 as a precursor. Ammoniation of Ga2O3 gel was conducted in the flow of NH3 gas at 950 ℃ for 20 min. Measurement results by XRD, FTIR, TEM, and SAED indicate that the synthesised GaN is of a single-phase hexa nal wurtzite structure, and the granularity of the GaN powder has a od uniformity. In addtion, the FTIR shows a distinct peak broadening.
