Comparative Studies of the Optical Absorbance and Structural Properties of Ironcopper Sulphide(CuS-Fe) and Iron Lead Sulphide(PbS-Fe) Thin Films Deposited by Silar Method

摘要

The influence of iron on lead sulphide(PbS) and Copper Sulphide (CuS) thin films deposited on glass substrates via successive ionic layer adsorption (SILAR) Technique using lead acetate, Pb(CH 3 COO) 2 , Cupric Acetate Cu(CH 3 COO) 2 , thioacetamide ( S 2 H 5 NS) , Iron (II) Chloride dehydrate(Fe Cl 2 . 2H 2 O), ethanol and ammonia by in alkaline medium annealed between 283K and 500K was investigated. The structural and morphological studies were performed by X-ray diffraction (XRD) Analysis and scanning electron microscopy(SEM) respectively. The Uv-visible studies were done using spectrometer in the Technical University, Ibadan. The XRD showed films of cubic crystalline PbS thin films, cubic and face-centred crystalline PbSFe thin films, cubic CuS thin film, hexagonal Cu 2 S thin films and cubic and hexagonal crystalline natured CuSFe thin films with the preferential (111),(002)(004) (311) orientations.
