Abstract

The dependence of resonance energy transfer from Wannier-Mott excitons to an organic overlayer on exciton dimensionality is studied experimentally and by means of supporting simulations. The variation of temperature effectively tunes the balance between localized and free excitons, and allows to investigate the effect of the excitonic potential disorder on resonance energy transfer. Our theoretical calculations give insight into the experimentally observed temperature dependence of resonance energy transfer, and allow us to quantify the contribution from localized and free excitons. It is shown that free excitons can undergo resonance energy transfer at a rate that is an order of magnitude higher compared to localized excitons. In planar geometries nonradiative resonance energy transfer is dominating over radiative energy transfer and hence we propose hybrid inorganic-organic LEDs which are optimized for resonance energy transfer to an organic or QD-based color converter.
