Abstract

A method is disclosed for the production of highly diffusive or absorptive metal surfaces. A dendritic crystal structure surface layer of metal is electrodeposited on a substrate, using a bipolar pulse plating technique. This metal surface layer may then be oxidized to provide a highly anti-reflective surface.
