ABSTRACT:
A highly ordered metal nanohole array (platinum and gold) was fabricated by a two-step replication of the honeycomb structure of anodic porous alumina. Prepn. of the neg. porous structure of porous alumina followed by the formation of the pos. structure with metal resulted in a honeycomb metallic structure. The metal hole array of the film has a uniform, closely packed honeycomb structure approx. 70 nm in diam. and from 1 to 3 .mu.m thick. Because of its textured surface, the metal hole array of gold showed a notable color change compared with bulk gold.
