Paper Abstract

Photoinduced changes in luminescent and photoelectrical properties of the hybrid structure based on CdSe/ZnS QDs and multilayer graphene nanobelts were studied. It was shown that an irradiation of the structures by 365 nm mercury line in doses up to 23 J led to growth of QD luminescent quantum yield and photocurrent in the QD/graphene structures. This confirms the proximity of the rates of the QD luminescence decay and energy/charge transfer from QDs to graphene, and opens an opportunity to photoinduced control of the photoelectric response of the graphene based hybrid structures with semiconductor quantum dots.
