PbS nanorods were synthesized hydrothermally at 120℃ for 12h, by using Pb(CH3COO)2•3H2O and CH4N2S as raw materials, cetyl trimethyl ammonium bromide (CTAB) and sodium dodecyl sulfonate (SDS) as surfactants. The as-prepared samples were characterized by X-ray powder diffraction (XRD), high resolution transmission electron microscope (HRTEM) and transmission electron microscope (TEM). The results show that the as-prepared PbS nanorods are with a cubic single phase, rod-like morphology and single crystalline nature. The effects of both molar ratio between reactants and reaction temperature on the products were investigated.

Key words: PbS, nanorod bundle, hydrothermal synthesis
