Variation of Band Gap Energy and Thickness with Temperature of Solid Solution II-VI CdZnSe Thin Films Prepared by Spray Pyrolysis

Y. D. Tembhurkar

Abstract: CdZnSe thin films were prepared by using aqueous solution of cadmium chloride, zinc chloride and selenium dioxide of 0.01 M of each. Optical band gap calculated from the graph (h) 2 verses h. This indicates that the optical band gap decreases as temperature increases uptooptimised temperature. If further increase of temperature the optical band gap increases and thickness decreases. This is due to higher evaporation the initial ingredient. The band gap energy decreases from 1.88 eV to 1.78 eV as temperature increases. CdZnSe thin films shows the direct allowed transition.
