Preparation and physical characterization of CdS thin films deposited by chemical spray pyrolysis

Authors(1) :-Hadi Ahmed Hussin

Optical absorbance spectra of CdS thin films were recorded from UV-Visible spectrophotometer in the range 380-900 nm. The films were prepared by chemical spray pyrolysis by spraying an aqueous solution of cadmium chloride (CdCl2) and thiourea [(NH2)2 CS] with de-ionized water. The absorbance, refractive index, absorption coefficient increased with the increasing of CdS film thickness, while the extinction coefficient decreased. The energy gap decreased from 2.4 eV for thickness 500 nm to 2.37 eV for thickness 700 nm.<
