FIG. 1.

Solid black line: Time-resolved electroluminescence signal of the device. Dashed red line: Time dependence of the applied voltage. The inset depicts the device structure.

FIG. 2.

Simulation results. Solid black line: Calculated time-dependent singlet exciton density. Dashed red line: Time dependence of the applied voltage. The peak amplitude amounts to at and at .

Image of FIG. 3.
FIG. 3.

Calculated spatial distribution of charge carrier and singlet exciton densities. A positive voltage is applied, i.e., holes are injected at the metal-organic interface. (a) Charge carrier distribution shortly after the voltage has changed to positive polarity. (b) Carrier distribution at the time of the largest exciton generation rate. (c) Shortly before polarity reversal.

Image of FIG. 4.
FIG. 4.

Calculated spatial distribution of charge carrier and singlet exciton densities. Voltage polarity is negative, i.e., electrons are injected at the metal-organic interface. (a) Charge carrier distribution at the time of the largest exciton generation rate. (b) Spatial distribution of carriers at voltage minimum.
