Abstract

Fe-doped TiO2 nanoparticles were synthesized by sol–gel method. The synthesized nanopowders were characterized by powder X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), Ultraviolet Visible (UV-Vis) and Dielectric studies. The crystallite size and phase were determined by X-ray diffraction (XRD) analysis. The morphology and particle size were studied using the scanning electron microscope (SEM) and transmission electron microscopy (TEM). There is a slight variation in numerical value of crystallite size measured by the two techniques: TEM and XRD peak broadening. The optical properties were obtained from UV-Vis absorption spectrum. The UV-Vis absorption spectrum demonstrated an absorption shift in Fe-doped TiO2 nanoparticles to longer wavelengths, thus showing an enhancement of the absorption in the visible spectrum. The dielectric studies were carried out at different frequencies and at different temperatures for the prepared Fe-doped TiO2 nanoparticles. The frequency dependence of the dielectric constant and dielectric loss is found to decrease with an increase in the frequency at different temperatures.
