Abstract

Sn and La co-doped TiO2 thin films were fabricated on surface of glass slide substrates. Co-doped titania thin films were prepared by a sol gel method using, TBT as a precursor. Morphology and crystallite size of the obtained co-doped thin films changed by changing the content of La. Accordingly, the doped titania thin films showed various water contact angles and optical band gaps. As, the optical band gap of the nanostructured doped titania thin films decreased with increasing in content of La from 3.4 to 2.32 eV. Moreover, the water contact angles changed from 69.0° to 13.5° by changing the content of La.
