Abstract
The present disclosure provides a composition comprising a hierarchical opal that exhibits structural color when exposed to incident electromagnetic radiation. The hierarchical opal comprises nanoscale periodic cavities separated by a lattice constant, and includes a surface having grooves. The grooves may form a diffractive optical element on the surface of the hierarchical opal, such as a diffuser, a diffraction grating, a beamsplitter, a beam displacement opic, a Fresnel lens, and a micro lens, among others.
