✦ Synopsis

Cadmium-Iron-Sulphide (Cd-Fe-S) thin films have prepared on indium doped tin oxide (ITO) coated conducting glass substrates by potentiostatic electrodeposition technique. X-ray diffraction pattern shows that the deposited films exhibit mixture of hexagonal CdS and hexagonal FeS phases. Surface morphology and film composition represent that films with smooth surface and better stoichiometry are obtained at 0.0375 M CdSO 4 concentration. Optical parameters such as band gap, refractive index and extinction coefficient which are evaluated from optical absorption measurements. The experimental observations are discussed in detail.
