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.

Synthesis, Characterization and Optical Properties of Nano Structure Lead Oxide

Several 2,5-dimethyl-N-substituted pyrroles were prepared by the condensation of different substituted anilines with 2,5-hexanedione using nano lead oxide as an efficient and recyclable catalyst. All the synthesized compounds are confirmed through IR, 1H NMR, 13C NMR and mass spectral data. Nano lead oxide β-PbO (P85) was prepared by dissolving lead acetate dihydrate in 1-propanol at a pH 9.0 under stirring at 85 °C. The structural study and surface morphology of the lead oxide (PbO) were characterized using X-ray diffraction (XRD), Scanning electron microscopy (SEM) and the functional groups of the PbO sample were investigated using infrared spectrophotometer. © 2011 A.
