Structural and Optical Properties of Ti_1-xFe_x O₂ Nanoparticles

Abstract:

We have synthesized the Ti_1-xFe_x O₂ (x=0.01, 0.02, 0.03 and 0.05) nanoparticles by the sol gel method to enhance the photocatalyic property of TiO₂ .These samples are characterized using x-ray diffraction (XRD), Raman spectroscopy, Ultraviolet /Visible (UV/V) spectroscopy and fluorescence spectroscopy (PL). The x-ray diffraction patterns show that all the sample are formed in single phase with a complete solubility of Fe ions in the TiO₂ matrix. TiO₂ nanoparticles are tetragonal with anatase structure belong to the space group D₄¹_h⁹ (14₁ ) /amd Raman active modes appear at 150, 196, 396, 483, 516 and 637cm^-1. UV/V spectra show a decrease in the band gap with the increase in Fe concentration from 3.26 eV (1% Fe concentration) to3.11 eV (5% Fe concentration).
