Abstract: Nanoparticles of titanium dioxide doped with Fe2+ ions have been synthesized via sol-gel technique using Titanium tetraisopropoxide (TTIP) and ferrous sulphate as a precursors. The synthesized nanopowders were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Ultraviolet Visible (UV-Vis) and Photoluminescence (PL) Spectroscopy. PXRD pattern indicates the presence of pure crystalline anatase phase TiO2 with average crystallite size of 14 nm. FTIR spectra showed the vibrational bands of Ti-O networks. The morphology of the as prepared samples and chemical constituents of the nanoparticles studied using SEM and EDAX analysis. From the UV-Vis spectra and PL spectra the optical properties of TiO2 were studied and discussed
