Structural and Optical Properties of TiO2 Nanoarray Films Prepared by Liquid Phase Deposition

摘要：

　　In this paper,highly ordered TiO2 nanotube array films were fabricated by liquid phase depostition method,based on different anodized aluminum templates.The surface morphology,structure and diffuse reflection spectrum were analyzed by X-ray diffraction,scanning electron microscopy,UV diffuse reflection spectrum.The results show that the crystal structure of the TiO2 nano array was anatase after heat-treating at 400℃.Scanning electron microscopy photographs show that nanobube arrays have an average diamieter of 50~80nm,the surface morphology is flat,and the tublar structure is not violated after heat-treating.As the growth time increased,red-shift effect was observed in diffuse reflection spectra.The optical band gap is respectively 1.48eV,1.70eV and 2.08eV as the growth time is 10mins,20 mins and 30mins.
