초록

In this study, The cathode interface layer (CIL) was investigated using aromatic diamine derivatives. Cz-TPD (4,4'-biscarbazolyl (9)-biphenyl) used in the cathode interface layers is investigated emition charcaracteristics at the green organic electroluminescent devices TPD (N.N'-dyphenyl-N-N'-bis(3-methy phenyl)-1.1'-biphenyl-4.4'-diamine) as the hole transformer layer and $Alq_3$:tris (8-hydroxyquinoline) aluminium) as the electron transport layer and emiting layer maded use of the organic electroluminescent device. The Organic Electroluminescent Device with Ag, cathode and CIL of Cz-TPD(4,4'-biscarbazolyl(9)-biphenyl) showed good EL characteristics compare to a conventional Mg:Ag device and also an improved storage stability.[1] As the change in MgAg, Cz-TPD/Ag, Ag at the chthode, the electron and optical charcaracteriseics were investigated.
