Fabrication and optical properties of gold nanowire arrays

In this work the optical properties of arrays of gold nanowires in transmission and attenuated total reflectance (ATR) geometry has been examined further, with a view to maximising the sensitivity by finding optimum nanowire and array dimensions. Gold nanowire arrays were grown by electrochemical deposition into a nano-porous alumina template. The effect of changing the nanowire aspect ratio on the optical properties was investigated.
