In this article, ZnO:Cd films were successfully deposited on glass substrates by a sol-gel technique. The influence of doping concentration and annealing temperature effects was carefully investigated. All films exhibited c-axis preferential orientation and optical transparency with visible transmittance >80%. The minimum room temperature resistivity of 0.0341 Omega cm was obtained with 10 at.% Cd doping under 600 degrees C annealing temperature. The optical band gap of ZnO: Cd film was reduced as Cd doping concentration increased, while the band gap increased with the increase of annealing temperature. (C) 2011 Elsevier B.V.
