| 英文摘要 | In Cu-I complex based organic light emitting diodes (OLEDs) a host matrix is traditionally thought to be required to achieve high efficiency. Herein, it is found that the device ITO/MoO3 (1 nm)/4,4'-N,N'-dicarbazole-biphenyl (CBP, 35 nm)/[Cu(mu-I)dppb](2) (dppb = 1,2-bis[diphenylphosphino]benzene, 20 nm)/1,3,5-tris(N-phenylbenzimidazole-2-yl)benzene (TPBi, 65 nm)/LiF (1 nm)/Al (100 nm) with a vacuum thermal evaporated nondoped Cu-I complex emissive layer (EML) showed external quantum efficiency and current efficiency of 8.0% and 24.3 cd/A at a brightness of 100 cd/m(2), respectively, which are comparable to the maximum efficiencies reported in an optimized doped OLED with the same emitter, higher efficiency than the OLED with a [Cu(mu-I)dppb](2):CBP EML, and much higher efficiencies than the nondoped OLED with a bis(2-phenylpyridine)(acetylacetonate)iridium [Ir(ppy)(2)(acac)] EML. A series of reference films and single carrier devices were fabricated and studied to understand the difference between Cu-I and IrIII complex based nondoped OLEDs. (C) 2014 Elsevier B.V.
