摘要：

Capping an indium-tin-oxide anode with a thin layer of praseodymium oxide (Pr2O3) has been found to enhance not only hole-injection, quantum, and power efficiencies but also the lifetime of organic light-emitting diode made using copper (II) phthalocyanine as the anode buffer layer, N, N-'-diphenyl-N,N-' bis(3-methylphenyl-1,1(')-biphenyl-4,4(')-diamine as the hole-transport layer and tris-8-hydroxyquinoline aluminum as the electron-transport/emission layer. The best results have been obtained on diodes with similar to1 nm thick Pr2O3. A possible mechanism behind the improvement is discussed. (C) 2002 American Institute of Physics.
