Synthesis and Characterization of Bio-Template Assisted Lead Oxide Nanoparticles
R. Bapitha, M. Alagar*

A new attempt adopted to synthesize eco-friendly lead oxide nanoparticles. In the present work, uncapped and corn starch capped lead oxide nanoparticles were synthesized by microwave - assisted route. The results of XRD studies revealed that the synthesized lead oxide nanoparticles have high purity and crystallinity. The approximation method which is the theoretical method of calculating the particle size and microstrain of synthesized nanoparticles was successfully applied. The presence of Pb-O band in FT-IR spectrum affirmed that synthesized nanoparticles were lead oxide nanoparticles. The spherical shape of uncapped lead oxide nanoparticles were tuned to rod like shape due to addition of corn starch which was observed by SEM morphology analysis. The energy gap of synthesized nanoparticles was estimated from the UV-Vis absorption spectra of synthesized lead oxide nanoparticles. The higher value in energy gap of lead oxide nanoparticles than its bulk one, confirmed that the size of the synthesized particles were in nano range. The AC impedance studies have been performed to measure the grain boundary resistance of both capped and uncapped lead oxide nanoparticles.
