摘要:
An organic EL device includes: an anode (3); a cathode (4); and an organic thin-film layer (5) provided between the anode (3) and the cathode (4). The organic thin-film layer (5) includes: a fluorescent-emitting layer (51) containing a fluorescent host and a blue fluorescent dopant; a red phosphorescent-emitting layer (52) containing a red phosphorescent host and a red phosphorescent dopant; and a green phosphorescent-emitting layer (53) containing a green phosphorescent host and a green phosphorescent dopant. The red phosphorescent dopant emits light mainly by receiving transfer of triplet energy from the fluorescent host. The green phosphorescent dopant emits light mainly by recombination of charges within the green phosphorescent-emitting layer.
摘要(中):
有机EL器件包括:阳极(3); 阴极(4); 和设置在阳极(3)和阴极(4)之间的有机薄膜层(5)。 有机薄膜层(5)包括:包含荧光主体和蓝色荧光掺杂剂的荧光发光层(51) 含有红色磷光主体和红色磷光掺杂剂的红色磷光发光层(52) 和含有绿色磷光主体和绿色磷光掺杂剂的绿色磷光发光层(53)。 红色磷光掺杂剂主要通过接收来自荧光主体的三重态能量的传递来发光。 绿色磷光掺杂剂主要通过绿色磷光发光层内的电荷再结合发光。
