| 摘 要： | 近年来，利用化学和物理方法制备各种高度有序的纳米结构材料已经成为学术界的研究热点之一．其中，在特定的模板中沉积各种材料而构建纳米点阵的方法，具有制备简便，成本较低等优点，而且在尺度上可以突破刻蚀技术的局限性，具有广泛的应用前景［１］．常用的模板有阳极氧化多孔铝（ＡＡＯ）、多孔硅和聚合物等，其中ＡＡＯ模板具有耐高温，绝缘性好，孔洞分布均匀有序，而且大小可控等特点［２］，是使用较为广泛的一种．利用阳极氧化铝为模板，采用电化学方法［３～７］或压差注入法［８］制备有序的纳米粒子点阵，已经在润滑［９］、电…

| Abstract: | We prepared highly ordered porous aluminum anoxicoxide (AAO)templates containing uniform nanoscale pores. Gold nanowires with lengths up to 2～3 μm and diameter as short as 15 nm were fabricated by ac electrodeposition of gold into the uniform templates. The templates and nanowires were characterized by Transmission Electron Microscope (TEM), the diameter of the resulted nanowires was determined by the pore size of the AAOtemplates, and their length was in proportional to the deposition time. It was also found that the nanowires were composed of many small single crystals and could be as thin as the diameter of one single crystaLIf the pore size of the template was small enough. |
