Gold Nanowires Prepared by Template Synthesis Method

Abstract

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.

Key words: Microporous anodic aluminum oxide(AAO), Electrodeposition, Nanowire, Transmission electron microscope(TEM)
