Abstract: Cadmium sulphide film has been prepared in open-air atmosphere by sintering technique-using ZnCl2 as an adhesive source and glycol as a binder. The reflection spectra of covered sintered film of CdS are recorded by a spectrophotometer at room temperature in the wavelength range 300-700 nm. From reflection spectra, energy band gap has been determined. It is found that energy band gap of this film is 2.57 eV, which is the energy band gap of Cd0.8Zn0.2S. This is suggestive of the fact that Cd0.8Zn0.2S is a wide band gap semiconducting material. X-ray diffraction patterns also confirm the formation of Cd0.8Zn0.2S.
