The electrochemical template synthesis of high aspect ratio nickel nanocylinders in the track-etch membranes of polycarbonate having nominal pore size of the order of 80 nm is considered. The morphological and structural analyses have been carried out through scanning electron microscopy and X-ray diffraction respectively, while optical characteristics have been examined using photoluminescence setup. It has been observed that the fabricated nanostructures are crystalline in nature and their metallic characteristics do not change.
