Abstract

New approach to.... A strategy for production of monodisperse polymer microspheres coated with semiconductor (Cds) or metal (Ag) nanocrystals was described. In the first step, an ion exchange between the counter iions in the electric double layer of the latex microbeads and Cd2+ or Ag+ ions. In the second step, CdS or Ag nanoparticles were formed by treating the latex dispersion with Na2S or NaBH4, respectively. This paper conducts an ion exchange of NPs directly in the electrical double layer of the microspheres, which were later used in the fabrication of photonic crystals.
