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.
