Nano crystalline cadmium oxide (CdO) thin films have been deposited on glass substrates using perfume atomizer spray pyrolysis method on glass substrate at 2000C at different pH values. X-ray diffraction and scanning electron microscope studies confirmed the cubic structure of the deposited CdO films. The CdO films were polycrystalline in nature with cubic crystal structure showing preferential orientation along (111) direction. The UV studies showed that the CdO films prepared have an average optical transmittance of ~60% and the optical band gap varied from 2.38 to 2.57 eV for pH solutions of 7, 8 and 9, respectively. The effect of pH on the film thickness, grain size and Photoluminescence studies were also made and analyzed.
