Smits, E.C.P. de Boer, B. Kemerink, M. Janssen, R.A.J. de Leeuw, D.M. Publication year 2008 Abstract In organic light-emitting diodes (OLEDs), interface dipoles play an important role in the process of charge injection from the metallic electrode into the active organic layer.[1,2] An oriented dipole layer changes the effective work function of the electrode because of its internal electric field. The differences between the work functions of the electrodes and the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of the light-emitting polymer determine the injection barriers and, thus, the electron/hole current balance and light emission of an OLED. Therefore, the local light emission can be enhanced or suppressed by changing the work function on a local scale. This control of local emission is ideally suited for OLED-based signage applications, for example.
