Study of optical constants of IIVI solid solution thin films of CdZnS2 prepared by spray pyrolysis

Y. D. Tembhurkar

Abstract :

 CdZnS2  thin films deposited by spray pyrolysis by using aqueous solution of cadmium chloride, zinc chloride and thiourea of 0.02 M of each. The temperature of the substrate was maintained 3000C throughout the deposition. Optical band gap energy calculated from the plot of (αh?)2 verses h? was of 3.12 eV. It shows the direct allowed transition. The value of refractive index (n) and extinction coefficient (k) decreases with the increase of wavelength. It indicates that the value of n and  k obtained by this method are suitable for many scientific studies and technological applications such as, gas sensors, heat mirrors, transparent electrodes, solar cells and piezoelectric devices.
