| 中文摘要 | electrical and optical properties of organic light-emitting diodes (oleds) with a stepwise graded bipolar transport emissive layer for a better control of charge transport and recombination are presented. the graded bipolar transport layer was formed by co-evaporating a hole-transporting material n,n-'-diphenyl-n,n-'-bis(1,1(')-biphenyl)-4,4(')-diamine (npb) and an electron-transporting/emissive material tris-(8-hydroxyquinoline) aluminum (alq(3)) in steps, where each step has a different concentration ratio of npb to alq(3). compared to a conventional heterojunction oled, electroluminescence efficiency was enhanced by a factor of more than 1.5, whereas the turn-on voltage remained unchanged in the graded structure. |
