QUENCHING OF PHOTOLUMINESCENCE IN AN ORGANIC DEVICE

摘要

The present invention relates to electric field quenching devices (FQD) comprising at least two electrodes (101,102) and an active layer (104) in between the said at least two electrodes, characterized in that the active layer comprises at least one phosphorescent emitter compound and a charge transporting host compound. Furthermore, the present invention relates to a display comprising at least one of the electric field quenching devices according to the invention and a process for controlling and/or regulating photoluminescence.
