Abstract
Conference Title: 2014 Recent Advances in Engineering and Computational Sciences (RAECS) Conference Start Date: 2014, March 6 Conference End Date: 2014, March 8 Conference Location: Chandigarh, India Co (III) doped titanium dioxide (Ti1- xCoxO2) thin films with different Co volume ratios (x = 0.0, 0.05, 0.1, 0.15, 0.2) were successfully deposited using Sol-Gel route. X-ray Diffraction patterns revealed that the films were deposited with amorphous, anatase and rutile phases. These phases strongly influenced by annealing temperatures and doping profiles. By annealing at 500°C, the structure has changed from amorphous to the anatase crystalline state. The phase transformation from anatase to rutile was observed in the temperature range 600-700°C. However, with the doping of Co resulted in extended phase transformation temperature upto 700 °C. The lattice constants 'a' and 'c' were calculated from TiO2 (200), TiO2 (101) peaks and grain size using the Scherrer's formula for TiO2 (101) peak and these parameters increased with increasing the annealing temperature.
