Abstract

The preparation and characterization of optically uniform mesoporous TiO thin films that present a high regularity in the pore mesostructure and orientation is reported. In addition, these films of optical quality are crack-free as confirmed on the nanometer and micrometer scales by electron microscopy. These films showed overall good optical quality as well as a high degree of organization before and after removal of the organic template and consolidation of the inorganic network.
