Fabrication of fluorescent hollow capsule with CdS–polyelectrolyte composite films

CdS–polyelectrolyte (CdS–PE) clusters were synthesized by using polyelectrolyte as the stabilizing agent in the aqueous solution. The blue shift of UV–Vis and Fluorescent spectra, the TEM images show the formation of nanoparticles within the polyelectrolyte chains. Using the normal polyelectrolyte hollow capsules as template, the CdS–PE clusters as functional layer materials, the uniform organic–inorganic hollow microspheres have been produced by layer-by-layer (LbL) self-assembly technology.
