Drawing on nature, synthetic opals (e.g., gilsonite) consist of uniformly sized ceramic spheres ordered into large close-packed domains. In order to improve the toughness or appearance of these chemically bonded ceramics, a polymer is often infiltrated into the interconnected space between the packed spheres. In a similar fashion, colloidal crystal arrays of submicrometer silica or polymer spheres have been employed as templates for periodic porous solids. All the methods for preparing periodic macroporous materials share a common synthetic thread: first, the colloidal crystals are formed from monodisperse spheres; next, the void spaces are filled and solidified; finally, the template is removed by heat, by refluxing in a solvent such as THF (in the case of polymer spheres), or by soaking in hydrofluoric acid (in the case of silica spheres). The product, which can be thought of as an “inverse opal,” often exhibits the same iridescence as a natural opal due to the similarity between the periodicity of the wall structure and the wavelength of light.

TiO2 inverse opals, as well as used as photonic crystals, can be applied to the dye sensitized solar cells (DSSC), photocatalysis, and so on. In above applications, ordering of pore arrangement in TiO2 inverse opal is crucial as it determines the application effect of TiO2 inverse opal. In this paper, TiO2 inverse opals were prepared by infiltrating and removing of polystyrene (PS) colloidal crystal templates. Using scanning electron microscope (SEM), it is found that the pore structure of inverse opals can be tuned by using different heating temperature and different size of PS spheres, and ordering of pore arrangement is strongly affected by ordering of PS spheres alignment, heating temperature, and size of PS spheres.

Nanocrystalline Ag doped silica inverse opals were prepared by a sol-gel chemistry method via templating of polystyrene colloidal crystals. The ordered structures of colloidal crystal templates and inverse opals are characterized by scanning electron microscopy. Ag nanocrystals size is estimated as 20~30nm by Scherrer Formula from X-ray diffraction. The color and the stop band of the inverse opals are characterized by transmission spectrum. And five emission peaks of the nanocrystalline silver clusters are observed from fluorescence spectrum.
