摘要：
In this letter, we describe a high-efficiency organic polymer light-emitting heterostructure device with aluminum cathode fabricated on a thin, flexible plastic substrate. The device consists of a hole transporting (amine-fluorene) and an emissive (benzothiadiazole-fluorene) conjugated organic polymer layers. The best heterostructure device has a green light emission and a maximum luminance higher than 2000 cd/m(2). Device shows a maximum emission of similar to 56.2 cd/A and, accordingly, a maximum luminous and external quantum efficiency of similar to 9.0 lm/W and similar to 15%, respectively. This organic light-emitting diode performance is acceptable for flat panel display applications. (C) 2000 American Institute of Physics. [S0003-6951(00)01206-7].
