Synthesis, Characterization and Optical Properties of Nano Structure Lead Oxide

Abstract:

Nanocrystalline lead oxide was prepared by solvo-thermal technique at a temperature of 75 °C. X-ray diffraction studies show the formation of stable β - PbO at 75 °C and heat treated from 200 to 500 °C for 2 h. Scanning electron micrograph images reveal the change in morphology of PbO particles from spherical to rhombus shape at higher temperatures. The band gap of the material was estimated by Diffused Reflectance Spectroscopy (DRS) found to be 2.67 eV. Photoluminescence spectrum of all the samples exhibits several band peaks due to radiative transitions from defect levels and recombination process.
