Study of Optical Properties of Spray Pyrolytically Deposited II-VI Solid Solution of CdZnSe Thin Films

CdZnSe thin films prepared by using aqueous solution of cadmium chloride, zinc chloride and selenium dioxide of 0.01 M of each at 3000C on pre-heated glass substrate. The optical band gap energy is found to be 1.78 eV which is close value to earlier reported workers. The optical study reveals that the CdZnSe thin films shows the direct allowed transition.
