Photonic Crystals: Extreme Optical Properties Tuned Through Phase Substitution in a Structurally Optimized Biological Photonic Polycrystal (Adv. Funct. Mater. 29/2013)
The beetle Entimus imperialis forms photonic crystals with a bicontinuous cubic structure of the diamond type in cuticular scales that show brilliant colors within well-defined domains. On page 3615, H.-O. Fabritius and co-workers report how the beetles tune the structural parameters and composition of these biological photonic crystals to achieve opposite extremes for their optical properties: the brightest colors possible or a colorless appearance.
