Abstract
We report the electrical properties of copper(II)-phthalocyanine(Cu-Pc) as a hole injaction layer in organic light-emitting diode (OLED). OLEDs were constructed by the following material structure : indium tin oxaide (ITO)/ CuPc/ triphenyl-diamine (TPD)/ tris-(8-hydroxyquinoline)aluminum (Alq3)/4-(Dicyanomethlene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM)/ Al. we observed that the change of recombination zone by using a DCM detection thin layer (6 ${\AA}$) in a Alq$_3$ emitting layer. layer. Recombination zone was moved toward the cathode as the hole mobility increased due to the heat-treatment temperature of cupc layer increased.
