利用真空沉积方法在高定向石墨(HOPG)基底上直接制备了粒径分布较小的金纳米粒子.超高真空扫描隧道显微镜(STM)研究发现，在74℃退火后，表观直径为2.5?nm的金纳米粒子在HOPG基底上形成了排列均匀的准一维纳米粒子链，并且此金纳米粒子链结构稳定.在122℃退火后，不同粒径的金纳米粒子在HOPG基底表面上聚合长大形成了准一维金纳米线.这一发现为制备由金粒子组成的有序纳米结构开辟了探索途径.

We have investigated the growth of gold nanoclusters on the surface of highly oriented pyrolytic graphite in ultrahigh vacuum.Studies by ultrahigh vacuum scanning tunneling microscopy indicated that the size distribution of gold clusters was very narrow and quasi-one-dimensional chains of gold nanoclusters of approximately 2 nm diameter were produced after annealed at 74℃.And gold nanowires made of different sized gold clusters could also be formed after annealed at 122℃.These results suggest the viability of a new route to the creation of ordered nanoscale structures.
