Abstract

An organic electroluminescent device with a luminous efficiency of 20 lm/W, at 14 cd/m2, and an external quantum efficiency of 4.6% has been fabricated using a high Tg hole transport polymer, a small molecule emission layer, and a LiF/Al cathode. The device quantum efficiency can be increased by tuning the ionization potential of the hole-transport moieties. When tested under pulsed voltage mode, in air at room temperature, and without any encapsulation, the device showed a high peak brightness of 4.4×106 cd/m2 at 100 A/cm2 and an efficiency of 4.4 cd/A.
