Abstract:

Transient electroluminescence in an organic LED based on a thin polymeric film has been experimentally studied and theoretically analyzed. The calculated and experimental curves are both characterized by anomalous dispersion and universality, which can be regarded as a manifestation of field-induced charge-carrier diffusion in the nonequilibrium transport regime. It is shown that the charge-carrier time of flight corresponds to the time to reach half the steady-state radiation intensity, rather than the delay time of the electroluminescence relative to the beginning of the applied voltage pulse.

Keywords:

transient electroluminescence, time-of-flight, organic LED, non-equilibrium transport, field diffusion
