Abstract
Nanocrystalline TiO2 thin films are deposited by simple successive ionic layer adsorption and reaction (SILAR)method on glass and fluorine-doped tin oxide (FTO)-coated glass substrate fromaqueous solution. The as-deposited films are heat treated at 673K for 2 h in air. The change in structural, morphological and optical properties are studied by means of X-ray diffraction (XRD), selected area electron diffraction (SAED), scanning electron microscopy (SEM), Fourier transform infrared (FTIR), transmission electron microscopy (TEM) and UV–vis–NIR spectrophotometer. The results show that the SILAR method allows the formation of anatase, nanocrystalline, and porous TiO2 thin films. The heat-treated film showed conversion efficiency of 0.047% in photoelectrochemical cell with 1M NaOH electrolyte.
