The Influence of Photoinduced Processes on a Quantum Dot Surface on the Electron Transfer Efficiency in TiO2 Nanoparticle/Quantum Dot Structures

Resumo

The influence of photoinduced processes occurring on the surfaces of CdSe/ZnS quantum dots is considered in relation to the functional characteristics of hybrid TiO₂ nanostructure/quantum dot systems. Preirradiation of quantum dots is shown to achieve a threefold increase in electron transfer efficiency within these structures. Photoinduced processes are found to impact both the efficiency of nonradiative phenomena in quantum dots and the electron transfer in the indicated systems.
