Abstract

Undoped and Cu doped Cd0.9Zn0.1S thin films have been prepared on glass substrate by chemical bath deposition technique for different Cu concentrations from 0.01 to 0.04 at 80 C. Crystalline phases and optical absorption of the films have been studied by X-ray diffraction and UV-visible spectrophotometer. Elemental composition was studied by the energy dispersive X-ray (EDX) analysis and the microstructure was examined by scanning electron microscope. The average crystalline size of the films was calculated from X-ray line broadening and it is decreased from 3.2 to 1.6 nm for x=0-0.04 which was confirmed by SEM studies. Energy band gap was calculated from optical studies and is varied from 2..
