Abstract
In the present research work, in order to optimize the fabrication of CdS optical films, the effect of bath temperature  on structural properties of  CdS thin layers produced by chemical bath deposition method in the range of 60-750 C was investigated,.  CdCl2, NH4OH, and thiourea were used as the reactants at constant pH and deposition time. The results showed that by increasing of temperature from 60°C to 75°C, the structures of the films change from amorphous to nano crystalline. The thin layer produced at 75°C temperature showed superior optical properties as regards to the optical characteristics like transmittance and energy band gap values.
