| Abstract | An organic alternating current electroluminescence (OACEL) device based on 4,4'-bis(N-phenyl-1-naphthylamino) biphenyl (NPB)/1,4,5,8,9,11-hexaazatriphenylene (HAT-CN)/tris(8-hydroxy-quin-olinato) aluminum (Alq(3)) doped with cesium carbonate (Cs2CO3) internal charge generation unit is demonstrated. Maximum luminance of 299 cd/m(2) is observed for Alq3 doped with 10-(2-Benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H, 11H-(1) benzopyropyrano (6,7-8-I, j)quinolizin-11-one (C545T) fluorescent emission layer when driven with a peak-peak voltage of 80 V at 120 kHz. The key charge-generation role of NPB/HAT-CN interface is studied experimentally. Furthermore, influence of evaporation sequence of this internal charge generation unit on OACEL performance is investigated. This work demonstrated that the undoped charge generation unit NPB/HATCN, can also be a good candidate for charge generation unit of OACEL device. (C) 2014 Elsevier B.V. All rights reserved. |
