Abstract

The CBD technique was employed to grow CuS thin films of onto clean microscope glass slide substrates in which the bath was composed of very dilute copper chloride solution as a source of Cu²⁺ ions and thiourea solution as a source

of S^2- ions. Structural properties were investigated and characterized using X- ray diffraction. The effect of deposition time on absorbance was investigated on the deposited films.
