摘要

By applying polystyrene opals made by a vertical deposition method as the templates, a modified filling method and a well-controlled calcination process, we have successfully obtained a large-area ordered TiO2 inverse opal with a higher volume fraction (14.5%) and a visible photonic bandgap. The influences of the filling process and calcination conditions on the fabrication of the TiO2 inverse opal are investigated.
