摘要:

用高温高压苯热合成方法制备了GaP纳米晶,用X射线衍射、光吸收谱及透射电子显微镜对所得样品进行了分析测试.结果表明,GaP纳米晶在苯热条件下是亚稳定态的,反应时间过长及反应温度过高均不利于它的生成和生长.文中还讨论了晶粒度分布与合成条件间的关系,并进行了理论上的定性分析.

关键词: GaP纳米晶, 苯热合成, 光吸收

Abstract:

 GaP nanocrystals were synthesized by high temperature high pressure beuzene thermal synthesis method, the samples were charartrized by X-ray diffraction, optical absorption and transmission election microscope. The results showed that GaP nanocrystals were metastable under benzene thermal conditions. The relationship between the size distribution and the synthesis conditions was also investigated in this paper.

Key words: GaP nanocrystals, Benzene thermal synthesis, Optical absorption
