We use spectral kinetic methods to study electronic energy transfer processes between semiconductor quantum dots on the surface of wide-pore silica in the absence of and in the presence of silver nanoparticles, obtained by laser ablation methods. We have determined the efficiencies of dipole–dipole energy transfer between two-shell (CdSe/CdS/ZnS) and one-shell (CdSe/ZnS) quantum dots on the surface, the luminescence lifetimes and quantum yields, transfer distances and transfer rate constants. We have studied enhancement of photoprocesses in individual quantum dots and in a pair under the influence of resonant localized plasmons of ablative silver nanoparticles.
