A configuration transition from hexagonal, to cubic, and then to a channel-like structure was observed when the copolymer-templated thin film was thermally annealed from 110 to 450°C. In the mesoporous TiO2 film annealed at 450°C, mesopores were merged in a preferential direction, forming a channel-like structure consisting of a semicrystalline (anatase) framework. These films exhibit excellent optical transparency with transmittance higher than 85% in the visible region. A blue shift in UV-Vis absorption onset was shown for the mesoporous TiO2 films, indicating a size quantization effect of nanocrystalline titania. © Springer Science + Business Media, LLC 2006.||Source Title:||Journal of Electroceramics||URI:||http://scholarbank.nus.edu.sg/handle/10635/86928||ISSN:||13853449||DOI:||10.1007/s10832-006-9905-1|
