摘要：
Nanocrystalline lead oxide was prepared by solvo-thermal technique at a temperature of 75 degrees C. X-ray diffraction studies show stable beta - PbO is formed at 75 degrees C and remains in the same phase after heating upto 500 degrees 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 the samples exhibits several band peaks due to radiative transitions from defect levels and recombination process.
