Fabrication and photoluminescence property of CdS nanowire array by template electrodeposition

Abstract

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.
