Post-annealing effect of copper phthalocyanine on enhancing the performance of green organic light-emitting diode
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 [...]
