Spray Pyrolysis Growth of Cd0.92Mn0.04Fe0.04O Thin Films: Effect of Substrate Temperature on the Microstructural, Morphological and Optical Properties

Abstract

Cd0.92Mn0.04Fe0.04O thin films at different substrate temperatures were prepared by spray pyrolysis method using perfume atomizer. The effects of substrate temperature on micro-structural, morphological and optical properties are explored in detail. X-ray diffraction data revealed the presence of single phase cubic structure with purity. XRD analysis also confirmed the incorporation of Mn and Fe ions at Cd site into the host lattice structure. The morphology of samples was examined using SEM. The optical spectra showed the increase in the optical energy band gap and increase in transmittance with substrate temperature. Photoluminescence spectra showed emission peaks due to different defect states. The enhanced micro-structural, morphological and optical properties of Cd0.92Mn0.04Fe0.04O thin film pave the path for its potential application in the optoelectronic devices.
