Zusammenfassung: | An organic light-emitting device is disclosed. The organic light-emitting device comprises: an anode; a cathode; an organic layer which is interposed between the anode and the cathode and includes a light-emitting layer; and an exciton quenching layer interposed between the anode and the light-emitting layer and in direct contact with the light-emitting layer, wherein the light-emitting layer comprises a host and a dopant, and the exciton quenching layer comprises a quenching material, wherein T1 (lowest excited triplet energy level) of the quenching material is greater than or equal to T1 of the host, and T1 of the quenching material is greater than or equal to T1 of the dopant.
La présente invention se rapporte à un dispositif électroluminescent organique. Le dispositif électroluminescent organique comprend : une anode; une cathode; une couche organique qui est interposée entre l'anode et la cathode et comprend une couche électroluminescente; et une couche d'extinction d'excitons interposée entre l'anode et la couche électroluminescente et en contact direct avec la couche électroluminescente, la couche électroluminescente comprenant un hôte et un dopant, et la couche d'extinction d'excitons comprenant un matériau de trempe, T1 (niveau d'énergie de triplet excité le plus bas) du matériau de trempe étant supérieur ou égal à T1 de l'hôte, et T1 du matériau de trempe est supérieur ou égal à T1 du dopant.
