Paper Abstract

Hybrid structures based on CdSe/ZnS quantum dots and porphyrin molecules with effective energy transfer were formed in samples of polymer track pore membrane. It was observed that energy transfer efficiency depends on quantum dot size and correlates with overlapping integral between quantum dot photoluminescence and porphyrin absorption spectra inherent for Förster Resonant Energy Transfer, FRET. However, a noticeable deviation of experimental FRET efficiency dependence on an acceptor concentration from theoretical ones was observed for all donor-acceptor pairs. A gradient of donor and acceptor concentrations in the matrix is considered as the most probable reason of this deviation. A theoretical model describing energy transfer in a rigid solution with a gradient of particle concentration is proposed.
