| 摘 要： | 在空穴传输层N,N′-diphenyl-N,N′-bis-1-naphthyl-(1,1′-biphenyl)-4,4′-diamine(NPB)中掺杂电子传输材料Aluminium-tris-8-hydroxy-quinoline(Alq3)制备了有机电致发光器件。当掺杂浓度低于5%时器件仍为蓝光发射,但与同等结构没有掺杂的器件相比,蓝光器件的亮度提高了近20%,达到了12460cd/m2,外量子效率提高了15.5%。随着掺杂浓度的增加,光谱发生了从蓝光到绿光的红移,这种掺杂方案能够改善空穴和电子的注入平衡,使得空穴和电子在发光层中能够有效地复合,器件的色度、亮度和效率都有了相应的改变。

| Abstract: | We have fabricated the organic light-emitting devices(OLEDs)by introducing the electron transmission material aluminium-tris-8-hydroxy-quinoline(Alq3)into hole transport layer N,N'-diphenyl-N,N'-bis-1-naphthyl-(1,1'-biphenyl)-4,4'-diamine(NPB),whose doped concentration affects both color and efficiency of the devices.The OLED is still blue emission when the doped concentration of Alq3 is below 5%,compared to the blue devices with a same structure,the brightness increases nearly 20%,up to 12460 cd/m2,and qua... |
