Sol–Gel Synthesis and Characterization of TiO2 Nanoparticles
Titania (TiO2) nanoparticles were prepared by a low temperature sol–gel synthesis route and were characterized by X-ray diffraction, transmission electron microscopy and Raman spectroscopy. The effect of high energy electron beam irradiation on the Raman spectra of
anatase and rutile TiO2 nanoparticle samples was investigated using Raman spectroscopy. The Raman bands of the irradiated samples were modified and blue shifted. The present studies found that nonstoichiometry, defects and particle size variation caused by electron beam irradiation
have a great influence on the blue shift and band modification, which may result an increase of the photo-activity of the tested TiO2 nanoparticles.
