Abstract |
|
|
| Thin films of CuS were prepared by Successive Ionic Layer And Reaction (SILAR) method from solution of CuCl2 and Na2S at two different molarities (0.03 M and 0.06 M) on glass substrates at room temperature. The structural and optical properties of CuS films were determined using X-ray diffraction (XRD) and UV-VIS spectrophotometer respectively. The films are polycrystalline, very adherent to the substrate and well crystallized according to the centered cubic structure with preferential orientation along (103) . It was found that the energy gap of CuS varies from 2.4eV to 2.8eV for thickness of 0.55μm and 0.82μm respectively (i.e depending on the deposition conditions). |
