Abstract

The invention relates to an organic optoelectronic apparatus comprising: a first electrode (2), a radiation-emitting region (4) arranged between the first and second electrodes, and a second electrode (9), wherein the first and second electrodes can inject charge carriers of different polarity into the radiation-emitting region, wherein the radiation-emitting region (4) has a dual emitter and a further emitter, wherein the further emitter is transferred by the charge carrier into an electronically excited state and, on the transition into the basic electronic state from this electronically excited state, emits radiation, and wherein the dual emitter has a first electronically excited state and a second electronically excited state, which can be reached from the first electronically excited state by intramolecular proton transfer or intramolecular charge transfer, and the dual emitter has an emission starting from the second electronically excited state into a second basic state. The radiation emitted by this apparatus has an improved CRI value owing to the simultaneous use of a dual emitter and a further emitter.
