PbSe/Pb4SeBr6 nanocomposite synthesized by a simple and green acetate-paraffin route

摘要

PbSe/Pb4SeBr6 nanocomposite was synthesized by a simple and green Acetate-Paraffin route in the presence of Cetyltrimethylammonium bromide (CTAB). The phase composition of the product was confirmed by X-ray powder diffraction (XRD) and energy dispersive spectrometry (EDS). The morphology was characterized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The result indicated that the compound was composed of PbSe nanoparticles and Pb4SeBr6 microspheres. The composite shows complex optical absorption property of PbSe and Pb4SeBr6.
