Abstract
Cadmium Telluride nanoparticles were synthesized by the sonochemical method (ST) and deposited on the glass and ITO glass as transparent substrates at 100 °C. X-ray diffraction (XRD) analysis indicated the formation of CdTe cubic phase with a strong preferential orientation of (200) crystalline plane. The obtained particle size in this orientation was about 13.56 nm. The grain size of the prepared CdTe thin films was 12.33 nm and 12.42 nm for glass and ITO glass substrates, respectively. Scanning electron microscopy (SEM) analysis used to investigate the morphology of CdTe nanoparticles. The Ultraviolet-visible (UV–vis) spectroscopy measurements showed increasing of the optical band gap from 1.49 eV for CdTe powder to 1.51 and 1.61 eV for CdTe thin films on glass and ITO glass, respectively.
