Exciton diffusion dynamics in an organic semiconductor nanostructure

Optics InfoBase Conference Papers (2004)

Authors:

C Daniel, C Silva, LM Herz, D Beljonne, FJM Hoeben, P Jonkheijm, APHJ Schenning, EW Meijer

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)

Authors:

AC Morteani, P Sreearunothai, LM Herz, RH Friend, C Silva

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.
