Abstract

La présente invention concerne un dispositif électroluminescent comprenant une première couche polymère (1) comme une couche de transport de trous/blocage d'électrons et une deuxième couche polymère (2) comme une couche émissive de transport d'électrons, la première couche et la deuxième couche étant en contact électrique afin de former une interface capable de produire une émission de type exciplexe sur un courant passant dans l'interface. La première couche est dotée d'une possibilité de transport de trous supérieure à celle de la deuxième couche, et la deuxième couche est dotée d'une possibilité de transport d'électrons supérieure à celle de la première couche.
