Abstract

Nanostructured CdO thin films have been prepared on glass substrates by spray pyrolysis technique using perfume atomizer from fresh and aged (1, 2, 3 and 4 days) precursor solutions. XRD studies confirm that all the films exhibit cubic crystal structure with a (1 1 1) preferential orientation. The preferential orientation factor f(1 1 1) increases with an increase in aging the period of precursor solution. The 2θ value of the (1 1 1) plane shifts towards lower Bragg angles with aging inferring an expansion in the lattice volume of the aged films. Increased crystallite size is observed for the 3-days aged film for which minimum strain and dislocation density values are obtained. Optical transparency increases with an increase in aging period of the precursor solution and the optical band gap exhibits a red shift from 2.48 eV to 2.32 eV. Minimum resistivity of 0.78 × 10−2 Ω·cm is observed for the CdO film prepared from 3-days aged solution. The obtained results infer that the CdO film prepared from 3-days aged solution exhibits better physical properties than the others.
