Abstract:
Asy nchronous pulse ultrasonic spray pyro lysis technique was employed to deposit Cux S ( x = 1, 2) thin films on g lass. T he deposited films chemically close to CuS were found to be poly crystalline phases, the Cu2 S films were a mixture of polycr ystalline as well. The crystalline phase of particles w as hig hly depended on the molar ratio of thiourea to CuCl2 and the pyrolysis t emperatur e. XRD and XPS anlysis show ed pur e stoichiometric Cux S ( Covellite CuS, Chalcolite Cu2 S) . Raman shifts o f the films were measured at 472 cm- 1 ( Cu2 S) and 474 cm- 1 ( CuS) .
