Abstract

Spectroscopic ellipsometry was used to investigate the optical properties of a series of 2D-hexagonal and 3D-cubic mesoporous titania samples subjected to different annealing temperatures. Below a critical temperature, the dispersion of the index of refraction of the composite structure exhibits strong anisotropy, while above the critical temperature the structure reverts to an isotropic medium. Scanning electron microscopy and X-ray measurements corroborate the ellipsometry results.
