The effect of annealing operation on the crystalline structure and optical properties of thin films of CdZnO grown by sol-gel method

Authors

Abstract

In this paper, firstly CdZnO thin films with average thickness of about 155
nm were grown by spin sol-gel method on the glass substrates. The Prepared
films were annealed at 450 and 500 oC. Crystal Structure and optical
properties of the samples have been investigated by UV-VIS spectrophotometer,
X-ray diffraction, and scanning electron microscopy. The
results showed that the annealing process causes improvement in crystal
structure the layers. In addition, transparency the layers and their band gap < br />decrease when in annealing temperature increases.
