Synthesis and Electrical Properties of TiO2 Nanoparticles Using a Wet Chemical Technique

Abstract

TiO2 nanoparticles were synthesized using a wet chemical technique. The as prepared nanopowder was used for further characterization. The prepared TiO2 nanoparticles were characterized for phase composition, using X-ray diffractometry. The particle size and morphology were studied using Scanning electron microscope and transmission electron microscopy. The dielectric properties of TiO2 nanoparticles were studied in the different frequency range of 50Hz- 5MHz at different temperatures. The frequency dependence of the dielectric constant and dielectric loss is found to decrease with an increase in the frequency at different temperatures. Further, the electronic properties like valence electron plasma energy, average energy gap or Penn gap, Fermi energy and electronic polarizability of the TiO2 nanoparticles were calculated.
