Abstract
The luminescence efficiency of polymer light-emitting diodes is determined by the efficiency of radiative recombination of excitons. In a joint research programme, Leiden University and Philips Research are conducting a theoretical investigation on the dynamics of excitons in conjugated polymers. This article reviews part of the results obtained so far, describing the following phenomena: spectral diffusion, electric field-induced quenching, photobleaching and defect quenching.
