摘要：

Well crystallized PbS rods with the aspect ratios ranging from 2 to 12 were successfully synthesized in ethylenediamine by the so-called SSC route. X-ray powder diffraction, transmission electron microscopy and X-ray photoelectron spectra were used to characterize the as-obtained products. Several factors, such as temperature, synthetic procedure and solvent, which affect the morphologies of PbS nanoparticles were discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
