Abstract

A scanning electron microscope, X-ray spectrum, and UV spectrometer have been used in the examination of CaZnO3 perovskite thin films. Chemical Spry Pyrolysis (CSPD) technique was used in the preparation of the films from a mixture including different concentrations of KOH and a constant substrate temperature. The effect of KOH concentration was clear on the film’s transmittance, absorbance, and energy gap. The energy gap varied from 2.75 eV with 0.6 gm of KOH, up to 2.95 eV for 1.2 concentration, and finally, the energy gap became 3.1eV with 1.8 gm of KOH. In addition, the average grain size also decreased with KOH concentration, from 116 nm to 92 nm.
