The effect of photoinduced processes on the CdSe/ZnS quantum dots surface on the functionality of TiO2 nanoparticles/quantum dots hybrid structures has been studied. We demonstrate that pre-irradiation of QDs layers allows for a threefold increase in the photoinduced electron transfer efficiency in the structures. It was shown that photoinduced processes affect both the efficiency of nonradiative processes in QDs and electron transfer conditions in hybrid structures.

The luminescent sensory systems based on manganese-doped zinc sulfide quantum dots were developed for aqueous environment monitoring. The structural, optical and sensory characteristics of quantum dots were investigated. The mechanism of ZnS:Mn2+ interaction with methane in the aqueous media, as well as factors that have a primary influence on the formation of the sensory response in the reaction with methane, were determined.
