| Abstract | In this research we deposited CuS thin films by chemical spray pyrolysis at substrates temperature equal to (190200 o C) . The composition of the prepared films consist of from solution of Thiouria (NH2)2CS (TU) with four molar concentration (0.03,0.04,0.05 and 0.08 M) and Copper Chloride CuCl2.2H2O with molar ratio (0.01 M) were deposited on glass substrates, the rate of spraying approximately (10 ml/s.). As deposition and annealed films were studied, the results of X-ray diffraction showed that the films were polycrystalline with Hexagonal structure . The optical properties of CuS thin films recording by the transmittance and absorbance spectrum for wave length range (300-1100) nm, the results showed that the transmittance increases with increasing molar concentration of Sulfide source (TU) for as deposited and annealed films. It is noticed that the electronic transitions is directly allowed transition and the values of energy gap ranging between ( 1.6 – 2.5 ) eV corresponding to increasing of molar concentration of Thiouria. |
