Abstract: Thin films of iron sulphide were prepared by chemical bath deposition technique in aqueous solutions. The influence of complexing agent for the formation of thin films was determined. The structure, morphology and optical properties of thin films of iron sulphide grown on microscope glass slide were investigated by X-ray diffraction, scanning electron microscopy and UV-Vis spectrophotometer. The films deposited using 0.1 M of sodium tartrate indicated the highest number of FeS peaks and covered substrate surface completely based on X-ray diffraction data and scanning electron microscopy results, respectively. However, when the concentration of sodium tartrate was increased to 0.2 M and above, the number of FeS peaks decreased and the films showed incomplete coverage of material over the surface of the substrate with inhomogeneous grain size.
