Exciton diffusion dynamics in an organic semiconductor nanostructure
Optics InfoBase Conference Papers (2004)
Abstract:
We present ultrafast studies and Monte Carlo simulations of exciton diffusion dynamics in isolated supramolecular helices of conjugated oligomers. We model ultrafast energy relaxation, depolarization, and exciton bimolecular annihilation dynamics with unprecedented molecular detail.Ultrafast charge photogeneration and exciton regeneration at polymeric semiconductor heterojunctions
Optics InfoBase Conference Papers (2004)
Abstract:
We investigate photoexcitation dynamics in blends of electron and hole transporting conjugated polymers. Excitons that dissociate at the heterojunction can be regenerated efficiently via geminate-pair recombination and endothermic energy transfer from intermediate exciplex states.Morphology-dependent energy transfer within polyfluorene thin films -: art. no. 085201
