Реферат:	eng: Specific features of the formation of local fields in spherical composite nanoparticles containing metal cores surrounded by a silica shell with implanted dye molecules are studied. A system consisting of two closely located nanoparticles (dimers) is analyzed. It is shown that the field configuration in the dimer corresponds to a much more effective feedback than that in the case of individual spherical nanoparticles. The dynamics of the fluorescence field near a flat package of composite nanoparticles is studied numerically with due allowance for the enhancement of the dye fluorescence field, saturation of the energetic transition, and diffraction. It is found that close arrangement of nanoparticles leads under pumping conditions to the formation of high-intensity fields localized with time in the space of the nanoparticle package neighborhood.
