Abstract


Lead Sulfide nanoparticle was prepared successfully from aqueous solution of lead acetate, and yellow ammonium sulfide at room temperature under atmospheric pressure. The structure and morphology of prepared PbS nanoparticle were analyzed by X-ray diffraction and Scanning electron microscope. The as-prepared PbS semiconductor nanoparticle was Monodisperse and have a very narrow size distributions and narrow band gap than other semiconductor chalcogenide.  The result indicates that the obtained nanoparticle is cubic in nature with average grain size of 11 nm. The optical properties of the prepared PbS were characterized by using UV-Vis spectrometer, FTIR and photoluminescence spectroscopy.
