Paper Abstract

The effect of photoinduced processes on CdSe/ZnS quantum dots surface on the functionality of TiO2 nanoparticles/quantum dots hybrid structures was investigated. It is shown that preliminary irradiation of quantum dots makes it possible to achieve a threefold increase in the efficiency of electron transfer from quantum dot to TiO2 nanoparticle in these structures. It has been demonstrated that photoinduced processes affect both the quantum yield of quantum dots luminescence and the reactive oxygen species generation by structures under visible light.
