Abstract: Carbon opals, a form of colloidal crystal, are composed of ordered two-dimensional or three-dimensional arrays of Monodispersed Starburst Carbon Spheres (MSCS). Methods for producing such carbon opals include oxidizing as-synthesized MSCS, for example by heating in air, to increase surface charge. Such oxidation is believed to decrease settling rates of a colloidal suspension, enabling formation of an ordered colloidal crystal. Inverse opals, composed of any of a wide variety of materials, and based on a carbon opal template, have a reciprocal structure to a carbon opal. Inverse opals are formed by methods including: forming a carbon opal as described, impregnating a desired material into pores in the carbon opal to produce a hybrid structure, and removing the carbon portion from the hybrid structure.

Abstract: Processes of forming an irreversibly loose packed structure of particulate material useful as a photonic or phononic crystal are provided. Matrix material is infilled between particles and extends above the particles to form a particulate free matrix layer. Removing the matrix layer causes deformation of or exposes the spacing between the particles. The spaces are infilled by additional matrix material that when cured produces a supported and irreversibly loose packed crystalline structure of particles producing differing bandgaps and transmissive properties relative to the original structure. The processes provided allow for economical tuning of the transmissive properties of photonic or phononic crystals.
