The authors report on resonant energy transfer of nonequilibrium excitons in an amorphous polyfluorene donor CdSeZnS core-shell nanocrystal acceptor system. By time-resolved photoluminescence (PL) spectroscopy, they have investigated the PL decay behavior of the primarily excited polyfluorene in dependence of the concentration of the nanocrystals. The authors are able to demonstrate that the finite rise time of the PL transient monitored at the spectral position of the acceptor PL directly reflects the PL decay of the donor. © 2007 American Institute of Physics.
