Paper Abstract

We have realized an organic two-contact, light-emitting device with reduced exciton quenching and photon absorption at the metal cathode. Compared to a conventional organic light-emitting diode (OLED), the metal cathode is displaced by one to several microns from the light-emission zone. Electron transport between the cathode and the light-emission zone occurs by field-effect, and hence with an enhanced mobility compared to electron transport in a conventional OLED. The electrical characteristics and the opto-electronic performance of this light-emitting device are measured. Numerical simulations indicate that the electronic and excitonic characteristics are in good agreement with these measurements. Maximum singlet densities comparable to those in OLEDs can be achieved, while optical and excitonic losses are reduced. This might possibly result in optical gain.
