  Investigation of the Preparation and Characterization of Fe-doped TiO2 Nanoparticles
  Author(s): Sagadevan SSagadevan S
  
  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 visibl.. Read More»
