High yield synthesis of PbS nanocubes using one-step solid-state reaction in the presence of an anionic surfactant
PbS nanocubes have been synthesized by one-step solid-state reaction between Pb(DS)(2) (DS: dodecylsulfate, anion) and Na2S.9H(2)O. The nanocrystals were characterized by X-ray powder diffraction, Transmission electron microscopy, UV-vis absorption spectrum and X-ray photoelectron spectra. The research showed that the functionized surfactant lead dodecyl sulfate (LDS) played an important role in the formation of PbS nanocubes. (C) 2004 Elsevier B.V. All rights reserved.
