Abstract

A composite cathode of aluminum-lithium fluoride (Al-LiF), based on 8-tris-hydroxy-quinoline aluminum (Alq₃) as the light-emitting medium and N-N′-diphenyl-N-N′bis(3-methylphenyl)-[1-1′-biphenyl]- 4-4′-diamine (TPD) as the hole transport layer, showed an order to magnitude increase in performance compared to Al-only organic light emitting diodes (OLEDs). Using composite cathodes eliminates the need for a thin insulating layer to be deposited between the metal and the underlying organic layer, thus simplifying device geometry.
