Photonic polystyrene (PS) opals with face-centered cubic structure werefabricated by convective evaporation. The influences of substrate and its physicalproperties, as well as deposition conditions were investigated. It is shown that thesurface roughness must be less than about 30% of the bead diameter to form wellorderedopals, rendering substrates such as glass, ITO and quartz superior to thickKapton, ordinary tape, thermal release semiconductor tape, plastic and hydrophilicplastic HHNW W (Kemafoil). Periodic stripe-like structures were found to formperpendicular to the growth direction defined by the receding meniscus of the solutionfront when the PS concentration is lower than 1.0 w/v%. Finally, we present theprinciples and results of using soft sacrificial layer deposited on quartz substrates tofabricate free standing inverse opal structures.1.
