INVESTIGATION ON STRUCTURAL AND OPTICAL PROPERTIES OF CADMIUM DOPED LEAD OXIDE NANOPARTICLES

Abstract: Cd-doped PbO is an inorganic metal oxide nanoparticle, was successfully synthesized by a simple microwave assisted solvothermal method. The prepared sample was characterized by using Powder X-Ray Diffraction (PXRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), UV-Visible spectroscopy (UV) and Photoluminescence (PL) spectroscopy. Using PXRD pattern, the average crystallite size was calculated as 74.09 nm. The morphology of the prepared Cd-doped PbO powdered sample was analyzed by the SEM micrograph. FTIR is a technique used to measure the vibrational frequencies of bonds in the molecule. Band gap of the Cd-doped PbO nanoparticle found using Tauc plots. PL emission spectrum of Cd-doped PbO nanoparticle was investigated. The emission spectrum revealed a blue emission.
