Baby incubation, copper sulphide(CuS), iron-doping, lead sulphide(PbS), structural and morphological studies


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 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. From the structural and morphological  studies, the iron lead sulphide,  and iron copper sulphide thin films can  be good materials for baby   incubation in neo-natal unit of hospitals and adapted in Ebonyi State University Abakaliki - Nigeria due to their new characteristics.
