ANALYSIS OF SILAR- DEPOSITED CuSFe THIN FILMS FOR OPTOELECTRONICS APPLICATION

The iron doping influence  on   Copper Sulphide (CuS)  thin films deposited on glass substrates via successive ionic layer adsorption and reaction (SILAR) Technique using  copper acetate,Cu(CH3COO)2  ,   thiourea,  Iron (II) Chloride dehydrate(Fe Cl 2. 2H 2 O) and Iron nitrate respectively, ethanol and ammonia   in alkaline medium annealed between  283K and 500K were 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 CuS thin film,polycrystalline  Cu 2 S thin films and cubic and nanocrystalline natured CuSFe thin films with the preferential (111),(002)(004) (311) orientations . The relatively high transmittance of  CuSFe thin films in the infrared region suggest that they may be used in physiotherapy for strained gyratrics patients bodies and joints. They are generally used in medical rehabilitation.
