Abstract
A two-step template-induced vertical deposition technique was introduced to fabricate the colloidal crystal heterostructures due to wettability differences and spatial confinement of the templates structured with microchannels. The heterostructures exhibited a bi-frequency Bragg diffraction whose position was determined by the microsphere diameter of the opals. It was demonstrated that the channel width had an influence on the optical properties of the colloidal crystal heterostructures. The strategy proposed is suited for fabrication of different micron-sized opal architectures with complex form and designed optical functionality.
