Optical properties of CdS nanowires prepared by dc electrochemical deposition in porous alumina template

Cadmium sulfide (CdS) nanowires on porous alumina template have grown by a simple dc electrochemical method. The microstructural study of the nanowires has been investigated using atomic force microscopy, field-emission scanning electron microscopy and transmission electron microscopy. X-ray diffraction spectra and Raman spectroscopy revealed the growth of polycrystalline CdS nanowires by filling the nanopores. Optical properties of CdS nanowires have been investigated at different growth temperatures using optical absorption, Raman and photoluminescence spectroscopy.
