Two-dimensional (2D) photonic crystals (PCs) of transparent TiO₂ gel rods, with a diameter in the range of 0.5 to 2.0μm, arrayed in a triangular lattice with a lattice constant between 1.0 and 4.0μm, were successfully fabricated from a titanium tetra-isopropoxide (Ti(OⁱPr)₄) ethylene glycol monomethyl ether (EGMME) solution using resist molds. The resist molds were fabricated on a Si wafer by electron-beam lithography. By casting the solution into the resist molds, we obtained TiO₂ gel PCs, which contained polyethylene glycol (55-60 mass%) used as a plasticizer, formed on gel plates with the same composition over an area of 500μm×500μm. This method enabled the preparation of dense, highly transparent TiO₂ gel PCs. Distinct changes in both reflected and transmitted colors were observed in the present gel PCs, demonstrating that they function as photonic crystals in the visible region.
