Abstract: Nanocomposite CdO-TiO₂ thin films had been deposited on conductive glass (ITO) at calcination temperatures in the range 350-650°C via. doctor blading method. The structural, morphological, compositional and optical properties have been characterized via XRD, SEM, AFM, EDS and UV-Vis spectroscopy. XRD patterns display the rhombohedral structure and crystalline nature of the films. All films were nanometerials according to Scherrer equation in XRD analysis. SEM images disclose the homogenous films in the form of densely packed nanoparticles. AFM analysis illustrated that both the surface roughness and grain size increase barely with growing temperature. EDS analysis confirms the presence of oxygen, cadmium and titanium elements with the function of cadmium-rich and titanium-poor. Agreeing with Tauc plots, optical band gaps of CdO-TiO₂ films are envisioned to be 1.25-0.9 eV.
