Abstract

Single layer coatings that render a surface more light transmitting and less light reflecting without an attendant increase in diffuse scattering are produced by depositing a thin metal film on the surface, totally converting the thin metallic film to either an oxide and/or hydroxide microstructured layer by chemical or a combination of chemical and electrochemical methods. Uniform optical properties are exhibited over large angles of incidence and an extremely broad range of wavelengths.
