介绍了一种由硝酸镓(Ga(NO3)3)和氨水溶液的混合物在700-900℃的氨气中合成纳米氮化镓(GaN)颗粒的简单方法。得到了平均直径约为20-50 nm的纳米GaN颗粒。得到的GaN纳米颗粒在254 nm紫外光激发下，在364 nm处显示出强烈的光致发光。考察了温度、加热时间、氨气浓度等制备条件对纳米粒子结晶度和光致发光强度的影响。
A simple method for the synthesis of nanosized gallium nitride (GaN) particles from a mixture of gallium nitrate (Ga(NO3)3) and aqueous ammonia solutions under a flow of ammonia gas in a temperature range of 700–900 °C is described. Nanosized GaN particles with an average diameter of approximately 20–50 nm were obtained. The resulting GaN nanoparticles showed an intense photoluminescence at 364 nm under UV excitation at 254 nm. The effects of the preparation conditions, such as temperature, length of heating time and ammonia concentration on the crystallinity and intensity of the photoluminescence of the particles were also investigated.
