Abstract:
The technique of introduction a fluorescent dye Tris(bipyridine)ruthenium (II) chloride into nanoparticles of silicon
dioxide in isopropyl alcohol was tested. The preparation of nanoparticles was carried out by means of the Stober method.
The optimal reaction conditions were determined. It was found out that the penetration of a dye into silicon dioxide
nanoparticles reduced the effect of concentration quenching of the dye and made it possible to achieve an increase in
fluorescence intensity in the solution more than twofold. An attempt was made to functionalize the obtained particles by
introducing amino groups onto the particle surface. Fused silver nanoparticles were seeded with silver nanoparticles.
