The electrical and optical Properties of the OELD using the Cz-TPD for cathode interface layer

음극접합층으로 Cz-TPD를 사용한 OELD의 전기적 광학적 특성

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-hyd-roxyquinoline) 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 electrical and optical charcaracteriseics were investigated.
