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. Keywords : Copper Sulphide thin Films: Lead Sulphide thin Films: Absorbance: structural properties DOI : 10.7176/APTA/82-04 Publication date: January 31 st 2020
