Abstract

This paper demonstrates photoinduced dissociation of complexes of CdSe/ZnS quantum dots with molecules of 1,2-pyridylazo naphthol under the action of external radiation of various spectral compositions and powers. It is found that energy transport from the quantum dots to the azo dye molecule appreciably contributes to the dissociation rate of the complexes. An analysis of the dissociation rate made it possible for the first time to experimentally estimate the efficiency of intracomplex energy transfer under conditions in which no luminescence of the acceptor is observed.
