| Abstract: | Asynchronous pulse ultrasonic spray pyrolysis technique was employed to deposit Cu x S ( x =1,2) thin films on glass. The deposited films chemically close to CuS were found to be polycrystalline phases, the Cu 2S films were a mixture of polycrystalline as well. The crystalline phase of particles was highly depended on the molar ratio of thiourea to CuCl 2 and the pyrolysis temperature. XRD and XPS anlysis showed pure stoichiometric Cu x S(Covellite CuS, Chalcolite Cu 2S).Raman shifts of the films were measured at 472?cm -1 (Cu 2S) and 474?cm -1 (CuS). |
