摘      要：Lead sulfide （PbS） nanostructures with different morphologies and particle sizes were obtained via a simple hydrothermal reaction between lead （Ⅱ） salicylate （Pb（Hsal）2） and thiourea （tu）. Reaction products were characterized by means of X-ray diffraction （XRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, ultraviolet-visible （UV-vis） and Fourier transform infrared （FT-IR） spectroscopy. Morphology of the product, varying from star-like to dendritic, depends on the mole ratio of tu to （Pb（Hsal）2）, pH, and reaction time.
