Abstract

The ultraviolet and x-ray photoemission spectroscopy were used to analyze the hole-injection enhancement in organic electroluminescent devices with gold (Au)/CF_x anode. The enhancement was analyzed from Au into N,N′-bis-(1-naphyl)-N,N′-diphenyl-1,1′-biphenyl-4, 4′-diamine (NPB) by inserting between them a plasma polymerized fluorocarbon (CF_x) buffer layer. The results show that Au surface with CF_x reduced the hole-injection barrier to ∼1 eV. The reduction was due to the buildup of an interfacial electric field arising from the molecular dipolar characteristics of CF_x.
