Effect of Thickness on Structural and Optical Properties of CdO Thin Films Prepared by Chemical Spray Pyrolysis Method

Abstract

The crystallite size, texture coefficient, number of grains, dislocation density and micro strain were calculated. Field Emission Scanning Electron Microscopy results showed Multiple shapes nano structures as semispherical, plates and rods. The optical properties was studied in (300-900) nm wavelength range. The energy band gap Eg is in the range of (2.3–2.6)eV, the absorption coefficient value is high(α >104 cm-1) and its Suitable for solar cell uses.
