Abstract
This project was aimed to synthesize and deposit thin films of Ce doped TiO2 nano-material of different doping concentration on a conductive substrate (ITO) and characterize the structural, optical & electrical properties of Ce doped TiO2 thin films to study the current-voltage properties, charge transfer, charge storage capacity and the variation of charge storage capacity of the prepared thin films. The Ce doped TiO2 thin films were synthesized by sol-gel technique. The Structural characterization of thin films was performed to confirm the formation of nano-materials and the presence of doped Ce molecules in TiO2 by XRD, and FTIR. To asses the optical performance of synthesized thin films Photo-Luminescence and UV-DRS Characterization techniques were used and it was found that the band gap of thin films has decreased after doping with Ce; it was also observed that the films show better photo-excitation in the visible range of spectrum. The electrochemical characterization of thin films was performed by Potentiostat/Galvanostat in presence/absence of visible light source for Cyclic Voltammetry. Charging and discharging cycle of thin films were studied at different scan rate. From cyclic voltammetry curves the charge storage capacity and electrochemical capacitance (ultra-capacitance) were calculated. The thin films after doping showed improved charge storage and capacitance in presence of visible light.
Characterization Techniques: XRD, FTIR, PL, UV-DRS, UV-vis. Cyclic Voltammetry, Thin Film Capacitance.
