Effects of multi-deposition on the structural and optical properties of cds nanocrystalline thin film prepared by CBD technique

الملخص EN

Cadmium sulfide (CdS) nan crystalline thin films have been prepared by chemical bath deposition (CBD) technique on commercial glass substrates at 70 ºC temperature.

Cadmium chloride (CdCl2) as a source of cadmium (Cd), theorem (CS (NH2)2) as a source of sulfur and ammonia solution (NH4OH) were added to maintain the pH value of the solution at 10.

The characterization of thin films was carried out through the structural and optical properties by X-ray diffraction (XRD) and UV-VIS spectroscopy.

A UV-VIS optical spectroscopy study was carried out to determine the band gap of the nan crystalline CdS thin film and it showed a blue shift with respect to the bulk value (from 3.9-2.4eV).

In present work effects of thickness on the structural and optical properties of CdS nan crystalline thin films were discussed.
