Abstract: In this study, undoped and Fe3+ doped TiO2 thin films has been prepared via sol-gel method using the tetraethyl-orthotitanate as source of Ti and Fe(III) nitrate as source of Fe3+ doping. Scanning electron microscopy (SEM-EDX), X-ray diffraction (XRD), and UV*vis spectrum were employed to examine the effects of Fe element on morphology, structure, optical characteristics and photocatalytics behavior of TiO2 films. XRD patterns showed the presence of TiO2 anatase phases only, no other phase has been appeared. SEM image confirm the nanometric grain size of all samples and a low decrease in band gap were we increases the Fe doping percentage. It is also observed that no enhancement in photocatalytics activities of Fe doped TiO2 thin films.
