Effect of $\text{ZnCl}_2$ and $\text{CaCl}_2$ Concentration on the Optical and Structural Properties of Perovskite Structure $\text{CaZnO}_3$

Abstract

Thin films of cubic perovskite ($\text{CaZnO}_3$) was deposited using Spry pyrolysis deposition (SPD) method. The effect of many precursors concentration on the structural and optical properties of ($\text{CaZnO}_3$) thin films have been studied using scanning electron microscope SEM, X-Ray spectrum and UV- spectrum respectively. The transmittance and absorbance of the prepared films with wave length show a clear variation with precursors concentrations, in addition, the energy gap of the films were also varied from 2.7eV to 3eV. The SEM images and x-ray spectrum of the films shows also clear difference in the shape and structure of the films.
