Abstract
PbS nanocubes and nanorods were successfully synthesized through a facile route using hexadecylamine
(HDA) and tri-n-octylphosphine oxide (TOPO) as surfactants. The structure and morphology of the
as-prepared PbS nanocrystals were characterized by X-ray diffraction (XRD), transmission electron
microscopy (TEM), high resolution TEM. The morphology of the PbS was influenced by the variation in
lead source and organic surfactant. Particles in the shape of spheres, perfect cubes and rods were
obtained by variation in reaction conditions. A possible growth mechanism to explain the formation of
these PbS nanocubes and nanorods is also discussed.
