Fabrication of Hierarchical Flower Shaped PbS Crystals via Hydrothermal and Microwave Routes


Article Preview

PbS crystals of different morphologies and sizes were prepared by the reaction of lead acetate (Pb (CH3COO)2) and thiourea (CH4N2S) using cetyltrimethylammonium bromide (CTAB) as surfactant through hydrothermal and microwave methods. In hydrothermal process, reaction was carried out for different reaction time. The samples were characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM) and UV-VIS-NIR spectroscopy. The results demonstrate that the reaction method and reaction time play important role on the evolution of morphologies and sizes of PbS micro/nanocrystals.
