摘要
Resonant nonradiative energy transfer between close-packed PbS quantum dots is observed in continuous-wave and time-resolved fluorescence experiments. Samples of nominally a single dot size, and two dot sizes, were investigated. In both cases, the time-integrated fluorescence exhibits a substantial redshift compared to the emission from dots in solution, and energy transfer can be observed directly in spectrally resolved fluorescence transients.
