Characteristics Study of Nanostructured CdO Prepared by Spray Pyrolysis

Full Text PDF

Abstract:

In this paper, nanostructured cadmium oxide films were prepared by chemical spray pyrolysis technique.The structural, morphological and optical characteristics of synthesized films are investigated as function of concentration .AFM results revealed that the root mean square of surface roughness is increased with cadmium concentration. XRD investigation confirmed that the films are polycrystalline with cubic structure. SEM study displayed that the synthesized films have particle size in the range of 25-100nm depending on cadmium ion concentration. The optical properties revealed the films have maximum average optical transmittance of 78% for film sprayed with 0.1 M. The optical band gap of the CdO film prepared with 0.25 M was 2.65eV. The optical band gap increased as the film molarity.
