INVESTIGATION OF SILVER NANOPARTICLES PLASMONIC CHARACTERISTICS ON ADDITION OF SULFUR-CONTAINING COMPOUNDS
The obtaining of silver nanoparticles by restoration from sodium borohydride solutions is given in the paper. The addition influence of sulfur-containing compounds on silver nanoparticles plasmonic characteristics was studied. The obtained dispersions were researched by optical absortion. Concentration values of electrons N e, coefficient of attenuation of plasmonic oscillation y and volume part (share) NV, occupied by nanoparticles were evaluated using Mi theory. It was shown the change of in spectra of plasmonic absorpton depends on concentration of sulfur-containing molecules.
