Influence of Co Transplantation SnO2 Nano Film on the Structural and Optical Properties Using Radio Frequency Magnetron Sputtering

In this research, investigated characterization of pure and Cobalt doped Tin dioxide SnO2: Co with 3, 5 7wt% fabricated using radio frequency magnetron sputtering method deposited on glass surfaces. The results showed that prepared were nano films poly crystalline in form favored reflection permanently (110) plan, the crystallite size decreases as concentration increased 9-14 nm. optical properties represented by transmittance perspicuous cobalt transplantation SnO2 layers studied highest obtained was 91% decreased to 78% increased; wavelength range 300-900 nm due be increasing amount during deposition, leading a linear increase mobility carrier concentration, until threshold content overcome from point onward began decrease. Optical energy gaps determined gap reduced 3.50 eV 3.29 for concentration.
