CdO Thin Films Fabricated by a Simplified Spray Technique Using Perfume Atomizer with Different Molar Concentrations of Cadmium Acetate for Optoelectronic Applications

Highly transparent and conducting cadmium oxide thin films were deposited on glass substrates by a simplified spray technique using perfume atomizer. The films were prepared with different molar concentrations of cadmium acetate. The effect of molar concentration on the structural, morphological, optical and electrical properties was studied. XRD analysis showed that the films exhibit cubic crystal structure with (1 1 1) preferred orientation. With higher solution concentration, the orientation changes to (2 0 0) plane. A slight angle shift of 0.03º to 0.22º for the (1 1 1) peak and a shift of 0.003º to 0.015º for the (2 0 0) peak was observed in the films as the molar concentration changes from 0.025M – 0.1M. The film surface modifies, with grains taking different forms with increased molar concentration
