摘要: 利用水溶液法制备了Au纳米粒子水溶胶, 透射电镜观察, Au纳米粒子的平均粒径 为29 nm. 将此溶胶滴至干净的单晶硅(110)表面上, Au纳米粒子自组装形成分形结构. 通 过控制温度, 所得的分形结构表现出不同的形貌特点. 利用光学显微镜观察Au纳米粒子 的聚集分形生长过程, 用原子力显微镜对分形结构的表面形貌进行表征, 讨论了分形生 长机理.

Abstract: Colloidal Au nano-crystalline in aqueous phase was synthesized and analyzed by means of TEM (about 29 nm). When several drops of this solution were dropped onto a clean silicon wafer(110), a snowflake or dendrite fractal structure formed with water vaporized under natural circumstances. Such structures were investigated by virtue of optical microscope and AFM. The mechanisms of Au nano-crystalline fractal growth on silicon surface were discussed.

Key words: Au nano-crystalline, silicon surface, fractal
