High-quality PS colloidal photonic crystals were fabricated quickly from aqueous colloidal solutions by a vertical deposition method at certain temperature and liquid surface dropping velocities and its photonic band gap was at 626 nm.

High-quality silica colloidal photonic crystals were fabricated quickly from aqueous colloidal solutions by a vertical deposition method at certain temperature and liquid surface dropping velocities.

Based on the transmission characteration of optical fiber and the methods of fabrication colloidal photonic crystals,electric field-controlled method is used to fabricate colloidal photonic crystals with the photonic band-gap(PBG) in communications wavelength.

Three-Dimentionally Ordered macroporous titanium-silica mixed oxides were successfully synthesized by using polystyren sphere colloid crystal as the template and the sol of tetraethyl silicate and tetrabutoxy-titane as the filling fluid.

Three dimensionally ordered macroporous silica was successfully synthesized using latex sphere colloid crystal as template and sol of tetraethyl orthosilicate, water, ethanol and hydrochloric acid as filling fluid.

Periodic macroporous titanium dioxide were successfully synthesized using PS colloid crystal as templates which were made by centrifuging latex sphere, filling in the voids with sol of terabutoxy_titane, and then transforming into gel in situ and removing latex sphere by calcinations.

Polystyrene colloidal crystals were assembled by natural sedimentation,centrifugation and vertical deposition methods.

Polystyrene colloidal crystal films(PCCF) were assembled by vertical deposition method.

A novel supermacroporous cryogel with sulfo binding groups used in cation-exchange monolith was prepared by in-situ grafting of 3-allyloxy-2-hydroxy-1-propanesulfonic acid sodium salt (AHPSA) onto the pore surfaces of polyacrylamide-based cryogel.
