Evidence for temperature tndependent triplet diffusion in a ladder type conjugated polymer (2006)
Reufer, M., Lagoudakis, P.G., Walter, M.J., Lupton, J.M., Feldmann, J., Scherf, U.
We study the temperature dependence of triplet formation and decay by considering the phosphorescence dynamics in a prototypical conjugated polymer matrix. The dynamics of triplet formation as a...
Spin-conserving carrier recombination in conjugated polymers (2005)
Reufer, M., Walter, M.J., Lagoudakis, P.G., Hummel, B., Kolb, J.S., Roskos, H.G., ...
The ultimate efficiency of polymer light-emitting diodes is limited by the fraction of charges recombining in the molecular singlet manifold. We address the question of whether this fraction can...
Low-threshold polymeric distributed feedback lasers with metallic contacts (2004)
Reufer, M., Riechel, S., Lupton, J.M., Feldmann, J., Lemmer, U., Schneider, D., ...
Optical losses in waveguides comprising metallic contacts are thought to be a major hurdle to the realization of organic laser diodes. We demonstrate here that careful tuning of the waveguide mode in...
