In this study, various concentrations of Fe doped TiO2 nanoparticles have been successfully synthesized using the sol–gel method. A variety of characterization techniques as ultra-violet visible (UV–Vis) spectroscopy, X-ray diffractometer (XRD), vibrating sample magnetometry (VSM) and field emission scanning electron microscopy (FESEM) were employed to analyze the prepared nanopowders. XRD measurement confirmed the substitution of Fe ion without disturbing the tetragonal crystal system of TiO2. The crystallite size was found to decrease and lattice strain increases upon doping estimated by Williamson Hall plot. Furthermore, the average grain size calculated by FESEM found was between 10 and 30 nm for pure and doped TiO2. UV–Vis spectroscopy showed an increase in absorption accompanied red shift and increase in band gap energies from 3.36 to 3.62 eV with the addition of Fe. The FTIR spectroscopy was employed to confirm the presence of functional groups in the fabricated nanopowders. Upon mixing the saturation magnetization (Ms) varying from (2.12 to 1.51)10−2 emu/g was observed.
