Abstract
The ''semimetallic'' photonic band gap formed in a synthetic opal has been increased by depositing a layer (InP or TiO2) with high refractiv e index on the inner surface of opal voids, Reflectance spectra of the composites (nanolayers assembled within grating voids) are correlated with both the photonic structure of the opal and electronic structure of the semiconductor.
