The morphology of and photoinduced changes in the luminescent properties of hybrid structures on the basis of TiO2 nanoparticles and CdSe/ZnS quantum dots are studied. It is established that the morphology of the structures depends on the method of their formation and the type of stabilizer of the CdSe/ZnS surface. It is shown that a photoinduced decrease in the efficiency of nonradiative relaxation of the excitation in the quantum dots leads to an increase in the quantum yield of their luminescence and an increase in the efficiency of photoinduced charge transfer in hybrid structures.
