The polymer encapsulated magnetic nanoparticles were obtained by suspension polymerization of styrene in the aqueous dispersion of magnetite. Functionalization of capsules was carried out by adsorption of BaZrO(3)luminescent nanocrystals on the polystyrene shell. Followed oxidative polymerization of aniline on the capsule surface leading to the additional encapsulation of the microspheres by conducting substance-polyaniline. It was found that adsorption of BaZrO(3)nanocrystals on polystyrene shell leads to modification of CL spectra due to chemical interaction between polystyrene and BaZrO(3)nanocrystals.
