Abstract
We present a study on subwavelength-structured surfaces with optimized color properties and antireflection properties in the range of the visible spectrum. Problematic blueness of the nanostructured surface has been eliminated under viewing angles from 0 to by designing and optimizing the antireflective surface parameters. The rigorous diffraction theory is used to minimize the surface reflection by simultaneously keeping the chromaticity coordinates of the reflected light in the white domain. The theoretical results are experimentally verified, and the -chromaticity coordinates of the surface are shown to be independent of the structure of the surface on small periods.
