Published in: Journal of Nanoparticle Research
Abstract: A novel synthetic approach for the preparation of PbS micro-nanostructures with different morphologies has been reported. PbS micro-nanostructures with various morphologies such as stars, dendrites, hexapods, and cubes were synthesized by thermal decomposition of lead acetate and thiourea in ethylene glycol at 120 °C, in air, in the absence of any surfactant. The PbS micro-nanostructures were characterized using different analytical techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, diffuse reflectance spectroscopy, and photoluminescence spectroscopy. The effect of different synthetic parameters such as [Pb2+:S2−] ratio, decomposition temperature, time, and source of sulfur on the morphologies of PbS was investigated and the mechanism for the formation of micro-nanostructures with different morphologies has also been proposed. © 2016, Springer Science+Business Media Dordrecht.
