ABSTRACT

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.
