Abstract [en]

The dependence of resonance energy transfer from Wannier-Mott excitons to an organic overlayer on excitondimensionality is studied experimentally and by means of supporting simulations. The variation of temperatureeffectively tunes the balance between localized and free excitons, and allows to investigate the effect of theexcitonic potential disorder on resonance energy transfer. Our theoretical calculations give insight into theexperimentally observed temperature dependence of resonance energy transfer, and allow us to quantify thecontribution from localized and free excitons. It is shown that free excitons can undergo resonance energytransfer at a rate that is an order of magnitude higher compared to localized excitons. In planar geometriesnonradiative resonance energy transfer is dominating over radiative energy transfer and hence we propose hybridinorganic-organic LEDs which are optimized for resonance energy transfer to an organic or QD-based colorconverter.
