Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>We demonstrate the effective self-assembly of Au nanoparticles array by porous anodic alumina templates. It is interesting that 'triangular island' nanostructure appears on the surface of porous anodic alumina template. Every 'triangular island' arises in the adjacent area among three close holes. Using vacuum deposition and thermal dewetting, Au nanoparticles ordered hexagonal array is fabricated on the porous anodic alumina. During optical characterisation, the absorption peaks of Au nanoparticles array are red shifted as the incidence angle increases. Also, Raman scattering spectra intensity of Au nanoparticles hexagonal array nanostructure is a hundred times larger than the contrast substrate material.</p> </abstract>
