(FR) ÉLÉMENT ÉLECTROLUMINESCENT ORGANIQUE EN TANDEM
(JA) タンデム型有機エレクトロルミネッセンス素子
Abstract: front page image
(EN)Disclosed is a tandem organic electroluminescent element wherein a first light emitting unit (3), an intermediate unit (4) and a second light emitting unit (5) are laminated between electrodes (2) and (6) facing each other. The organic electroluminescent element is characterized in that the first light emitting unit (3) contains a blue fluorescent dopant and a red fluorescent dopant and the second light emitting unit (5) contains a red phosphorescent dopant and a green phosphorescent dopant.
(FR)L'invention concerne un élément électroluminescent organique en tandem dans lequel une première unité d'émission lumineuse (3), une unité intermédiaire (4) et une seconde unité d'émission lumineuse (5) sont stratifiées entre des électrodes (2, 6) qui se font face. L'élément électroluminescent organique est caractérisé en ce que la première unité d'émission lumineuse (3) contient un agent dopant fluorescent bleu et un agent dopant fluorescent rouge et en ce que la seconde unité d'émission lumineuse (5) contient un agent dopant phosphorescent rouge et un agent dopant phosphorescent vert.
(JA)対向する電極(2),(6)の間に、第一発光ユニット(3)、中間ユニット(4)及び第二発光ユニット(5)が積層されてなるタンデム型の有機エレクトロルミネッセンス素子であって、前記第一発光ユニット(3)は、青色蛍光ドーパントと赤色蛍光ドーパントを含み、前記第二発光ユニット(5)は、赤色燐光ドーパントと緑色燐光ドーパントを含むことを特徴とする有機エレクトロルミネッセンス素子。
