Preparation and characterization of Ag nanowire arrays in porous anodic aluminum oxide template

Ag nanowire arrays have been prepared by direct current electrodeposition in porous anodic aluminum oxide template from a composite electrolyte solution.The images of Ag nanowire arrays are obtained by scanning electron microscope(SEM) and transmission electron microscope(TEM),respectively.Selected area electron diffraction(SAED)are employed to study the crystalline morphology of Ag nanowire arrays.The relationship between the nanowires length and electrodeposition time is discussed.Their growth speed is about 5?μm/h.The TEM micrographs show that these nanowires have uniform diameter of approximate 200 nm.SAED pattern reveals that the Ag nanowire has a polycrystalline structure.
