Abstract

Hetero-opals were synthesized by successive crystallization of one opal film on top of the other film using monodisperse PS beads of a different diameter. As such, the transmission spectrum of a hetero-opal shows two main minima following the difference of the Bragg resonance frequencies of its constituents. Strong spatial and frequency anisotropy of the reflectance spectrum of hetero-opals was a straightforward consequence of this mismatch of the Bragg resonances.
