Abstract

ZnS/ZnO doped silica glass inverse opals were prepared by a sol–gel chemistry method via polystyrene colloidal crystals templating. After the infilling precursors were solidified in the void space among polystyrene spheres, the polymer templates were removed by calcinations and the doped silica glass films were generated with long-range order of the inverse replicas of the template arrays. The effective reflective index of the structure and reflective index of the doped silica glass is calculated by Bragg equation using wavelengths of optical stop band and periodicity diameters of the inverse opals. The result is well agreed with mixture rule approximation.
