Effect of Annealing Temperature on Structural and Optical Properties of (Cu, Al):ZnO Thin Film by Sol-Gel Method

Article Preview

Abstract:

The (Cu,Al):ZnO thin films were prepared on glass substrates by sol-gel spin coating technique.The effect of annealing temperature on the structural and optical properties of the (Cu, Al):ZnO thin film was investigated by means of X-ray diffraction and UV-vis spectrophotometer. It has been found that the grain sizes, Optical band gap and the preferred orientation growth of (002) plane were decreased with annealing temperature. the annealing temperature also played a significant role in the blue-shifted phenomenon.
