Abstract
Large area thin film photonic crystals consisting either of closely packed PMMA balls or their SnS2 replicas have been synthesized and tested. The photonic bandgap (PBG) of these structures demonstrates a tendency towards omnidirectionality and a subsequent increase of the refractive index contrast (RIC) in the inverted opal structure. In particular, the bandgap width in SnS2 replica exceeds that of PMMA opal by a factor of three. Observations of the PBG-related dip in photoluminescence spectra and the self-focusing of the emission of the dye/PMMA opal have proven the merit of quasi-three-dimensional photonic films in the control of light emission.
