| | Post-annealing effect of copper phthalocyanine on enhancing the performance of green organic light-emitting diode | | Authors: | S.Z. Chen, J.H. Jou, F.S. Tang, P.H. Chiang, C.Y. Chang | | Affilation: | National Tsing Hua University, TW | | Pages: | 128 - 132 | | Keywords: | OLED, copper phthalocyanine (CuPc), post-annealing effect | | Abstract: | Post-annealing copper phthalocyanine (CuPc) can effectively improve the efficiency of a green organic light-emitting diode, consisting of indium tin oxide/CuPc/N,N’-bis-(1-naphthyl)- N,N’-diphenyl-1,10-biphenyl-4-4’-diamine/tris-8-hydroxy-quinoline aluminum/lithium fluoride /aluminum. By annealing the device at 120 for 1 hr, the power efficiency was increased from 1.7 to 2.0 lm/W, with a required driving voltage dropping from 4.7 to 4.2 V. The improvement may be correlated to the smoothening of the CuPc surface upon annealing. |  | This paper is available to CTSI members in PDF© format. | | ISBN: | 1-4200-8502-0 |
