本文采用湿化学法，通过控制尿素的含量来合成纳米MN粉体。对前驱体盐的热分解途径及相应产物进行了深入的讨论。采用FTIR、XRD、SEM和TEM等手段对合成粉体的微观结构和形貌进行了表征。AlN的光致发光（PL）特性也被用来研究微结构缺陷。研究了尿素含量对氮化铝粉末纯度、晶粒结晶度、显微结构和形貌的影响。
In this paper, the urea content was manipulated to synthesize nano-size MN powders by a wet chemical route. The thermal decomposition pathway of the precursor salts and the corresponding products were discussed thoroughly. The microstructure and the morphology for both of the as-received and resultant powders were characterized by FTIR, XRD, SEM and TEM. The photoluminescence (PL) property of AlN was also used for the investigation of the microstructure defects. The effect of the urea content on the powder purity, grain crystallization, microstructure and the morphology of the AlN was studied seriously.
