Abstract

Cadmium sulphide (CdS) thin films were deposited on glass substrates in aqueous medium by Photochemical deposition (PCD) using different cadmium (Cd) sources: cadmium sulphate (CdSO4) and cadmium nitrate (CdNO3). The substrate held in an aqueous solution containing thiosulfate ions (S2O3 2-) and metal ions (Cd2+) ions is irradiated with UV light. The S2O3 2- absorbs the UV photons and release solvated electrons and sulphur (S) atoms which react with Cd2+to form CdS. Deposition of CdS using CdNO3by PCD is reported for the first time. Characterization of the films by XRD, SEM and AFM is presented.
