Abstract

Highly efficient and bright organic light-emitting diodes (OLEDs) have been realized using thin alkali compound films (TACFs) as the electron pump layer (EPL) in the tris-(8-hydroxyquinoline) aluminum (Alq₃) with conventional organic layers. By comparing the performance of the device as a function of position with the EPL, we propose the optimal position of the EPL in Alq₃. Experimental results show that the efficiency of device with EPL is four times higher than that without.
