Title (EN) ORGANIC ELECTROLUMINESCENCE ELEMENT
(FR) ÉLÉMENT ÉLECTROLUMINESCENT ORGANIQUE
(JA) 有機エレクトロルミネッセンス素子
Abstract: front page image
(EN) An organic electroluminescence element characterized in having, between a pair of electrodes (2, 9), at least two organic layers including a light-emitting layer (5), and a delayed fluorescence exciplex layer (7) containing a donor compound and an acceptor compound is highly efficient in generating a singlet excited state, and enables high luminous efficiency.
(FR) L'invention concerne un élément électroluminescent organique caractérisé en ce qu'il comprend entre une paire d'électrodes (2, 9), au moins deux couches organiques comprenant une couche électroluminescentes (5), et une couche à fluorescence exciplexe retardée (7) contenant un composé donneur et un composé accepteur hautement efficace dans la génération d'un état singulet excité, et permettant un rendement lumineux élevé.
(JA) 一対の電極間2,9に、発光層5と、ドナー化合物およびアクセプター化合物を含有する遅延蛍光エキサイプレックス層7とを含む少なくとも2層の有機層を有することを特徴とする有機エレクトロルミネッセンス素子は、一重項励起状態の生成効率が高く、高い発光効率が得られる。
