Abstract: CdS nanowire arrays were prepared by a new electrochemical method. XRD and TEM measurements show that CdS nanowires were composed of cubic and hexagonal phases, and the mechanism of deposition was discussed based on ion diffusion. The length of the nanowire can be controlled by electrochemical deposition time and the diameter can be controlled by the aperture of porous alumina template. The method of depositting nanowires on alumina template is a general route for preparing other nanowire arrays. The photoluminescence measurements show that CdS nanowires have three ultraviolet luminescence bands and one yellow-green luminescence band.
