Formation of CdS Nanoparticles on Polymer Spheres Coated with Polyelectrolyte/Dendrimer Multilayers
包覆多层聚电解质/树状大分子的聚合物微球表面CdS纳米粒的形成

Core-shell microspheres with polyelectrolyte multilayers were fabricated by electrostatic self-assembly of three kinds of polyelectrolyte,such as polyamidoamine(PAMAM),poly(diallyldimethylammonium chloride)(PDADMAC)and poly(4-styrenesulfonate)(PSS).Core-shell microspheres with CdS/polyelectrolyte multilayers were prepared by deposition and adsorption of CdS on the polyelectrolyte multilayers,and the CdS nanoparticles were formed in solution or polyelectrolyte layer,the formed core-shell microspheres had stable photoluminescence property.TEM was used to characterize the shape of core-shell microspheres and photonic properties of core-shell microspheres with CdS/polyelectrolyte multilayers were analyzed by UV-Vis reflectance and photoluminescence spectra.
