Abstract

A simple method for fabricating various silver nano-structures using porous anodic aluminium oxide templates is described in this work. Highly ordered, high aspect ratio, silver nano-wire arrays were successfully prepared using wet chemical processing and thermal annealing. In addition to the fabrication of nano-wires, silver nano-particles with dimensions around 5-10 nm have also been prepared using the same procedure. Preliminary optical transmission measurements of the nano-wire arrays are presented in this work for their consideration as a meta-material.
