Abstract

The Förster resonant energy transfer (FRET) in layer-by-layer assembled, water soluble semiconducting cadmium telluride (CdTe) quantum dots was studied. The spectrally resolved fluorescence spectroscopy showed spectral diffusion of the fluorescence signal for quantum dots within one layer. Fluorescence spectroscopy also revealed rapid (254 ps) energy transfer from small dot layers to larger dot layers. FRET rates were investigated by performing temporally and spectrally resolved measurements using streak camera combined with a spectrometer. The energy transfer rates of (134 ps)^-1 due to a large spectral overlap with acceptor nanocrystals within the inhomogeneous distribution of donor nanocrystals were also observed.
