| 中文摘要 | we present a high-efficiency tandem white organic light-emitting diode based upon a c-60/5,5 '''-bis( naphth-2-yl)-2,2': 5',2 '': 5 '',2 '''-quaterthiophene (nat4) organic heterojunction as a charge generation layer. a maximum current efficiency, maximum power efficiency, and maximum external quantum efficiency of 111.3 cd a(-1), 50.5 lm w-1, and 38.7%, respectively, are obtained. more importantly, the efficiency roll-off is greatly improved with only a slight roll-off to 109 cd a(-1), 40.3 lm w-1, and 38% at a luminance of 1000 cd m(-2). surprisingly, the electroluminescent spectrum is highly stable at all levels of luminance. furthermore, our tandem device shows better operational stability than a tandem device employing a conventional charge generation layer. it is concluded that the excellent charge generation, transport, and extraction in the c-60/nat4 organic heterojunction-based cgl is responsible for the high performances. |
