摘要: Colloidal crystal heterostructures composed of two different material systems (organic polystyrene colloids and inorganic silica colloids) have been fabricated on horizontal solid substrates with an inward-growing self-assembly method. Microstructure characterization results showed high quality the resultant colloidal heterostructures. Optical measurements clearly demonstrated presence stop bands as a consequence superposition from individual compositional crystals.
