Beschreibung
Zusammenfassung:	We synthesized new electroluminescence materials [(1,10-phenanthroline)(8-hydroxyquinoline)] Zn(phen)q. Temperature dependent of electrical properties of OLEDs using Zn(phen)q are studied to understand an electrical conduction mechanism. The current density-voltage characteristics are measured in the temperature range of 60 ~ 240 K, and analyzed them using a hopping model with exponential trap distribution. At temperature above 150 K, the hopping conduction with exponential trap distribution is dominant. And we have obtained a characteristic trap depth of E t = 0.12 eV.
