Abstract
In the current work, pure and copper doped cadmium oxide (Cd1-x Cux O, x=0, 0.02, 0.03) thin films are grown by sol-gel spin coating route. Optical transmittance is measured in UV, VIS and IR spectra; it is revealed that the copper improves the transmittance. The optical band gap increased with the doping. The room temperature electrical resistance was affected by copper doping. The AFM morphology reveals that pure CdO and Cu doped thin films are nanostructured.
