摘要

TiO2 was crystallized to form thin films on transparent conductive films in aqueous solutions. The films had assembly of acicular TiO2 nanocrystals on the surface. The crystals grew along c-axis to form acicular particles. Growth direction, i.e., c-axis was perpendicular to the substrates. Amount of dye adsorption increased with film thickness. The intensity of the photoluminescence originated from the dye adsorbed on the nano-structured films showed 3 times higher than that of thicker particulate films constructed of TiO2 nanoparticles (P25). Assembly of acicular crystals on the surface increased surface area and amount of dye adsorption.
