摘要：
In this work, TiO2-Al2O3 nano-composite films were deposited on glass substrates by the sol gel method. The structural and optical properties of TiO2-Al2O3 nano composite films were characterized for different Al2O3:TiO2 volume ratio in TiO2-Al2O3 solution. The crystal size of TiO2 nanoparticles in TiO2-Al2O3 nanocomposite films was determined for the different Al2O3:TiO2 volume ratios. Band gap energy values of the films were controlled by changing Al2O3:TiO2 ratios. The properties of TiO2-Al2O3 nano-composite films were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), ultraviolet-visible spectroscopy (UV-vis), scanning electron microscopy (SEM), spectrophotometer (Perkin-Elmer), and Fourier transform infrared spectroscopy (FTIR). SEM results showed flower-like TiO2-Al2O3 nano-composite films. (C) 2013 Elsevier Ltd. All rights reserved.
