Abstract: The ternary compounds cadmium lead telluride have been prepared by oxalic acid method. Thin films were coated on glass substrates by vacuum evaporation method (Hindhivac 12A4). The structural properties of the material have been studied using X-ray diffraction technique. The result shows that material is crystalline in nature and the peaks in the XRD graph of CdPbTe corresponds to cubic structure. The lattice parameter and grain size have been calculated. The surface morphology of the thin film is studied using Scanning Electron Microscope (SEM). The SEM analysis shows that surface of the film is uniform and crystalline in nature. Thicknesses of the films have been determined by gravimetric method. The optical absorbance and transmittance have been studied by using UV spectrophotometer in the range of wavelength 300-1100 nm. The optical band gap of this material is found to be 1.24 ev.
