Fabrication and Photoluminescence Property of CdS Nanowire Array by Template Eiectrodeposition

<正>CdS nanowire arrays were synthesized by altering current(AC)electrodeposition in the porous anodic alumina film prepared by aluminium anodizing in oxalic acid.These nanowires have a uniform diameter of about 45 nm corresponding to the pore size of the films used and length up to several microns. The X-ray diffraction(XRD)pattern indicates that the CdS nanowires crystallize in an hcp structure.Besides, photoluminescences(PL)of CdS nanowire arrays,characterized by spectrophotometer show that CdS nanowries embedded in porous alumina template increases the light-emitting intensity and induces a red shift of PL band.
