The pure and 2% Fe doped TiO2 nanoparticles were synthesized using simple sol-gel method involving an ethanol solvent in the presence of ethylene glycol (EG) as the stabilizer. The physicochemical properties were investigated by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), electron dispersive spectroscopy (EDS), diffuse reflectance spectrum (DRS) and photolumincense (PL) analyses. XRD analysis showed the tetragonal anatase structure in presence of Fe doping. The size of the nanoparticles (NPs) decreased to 29 nm by adding Fe content with less agglomeration. PL analysis showed that the intensity of photoluminescence decreases for doped sample, suggest decrease in recombination of the electron–holes pair. The UV-DRS analysis indicated that the band gape energy decreases to 3 eV for Fe doped TiO2 nanoparticles.
