dc.description.abstractIn this study, TiO2-SiO2 nano-composite films were synthesized on glass substrates with spin coating method. The optical and structural properties of TiO2-SiO2 films were determined for different SiO2:TiO2 volume ratios. The properties of TiO2-SiO2 nano-composite films were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), ultraviolet visible absorption spectroscopy (UV-vis), Perkin Elmer Lambda-900 spectroscopy. The band gap energy values of the films and the crystal size of TiO2 nanoparticles in TiO2-SiO2 nano-composite films were controlled by changing SiO2:TiO2 ratios. The activation energy for the particle growth of SnO2 nanostructured films, which was determined as 15.8 kJ/mol. (C) 2016 Published by Elsevier GmbH.en_US
