Abstract
An organic electroluminescent device with a luminous efficiency of 20 Im/W, at 14 cd/m(2), and an external quantum efficiency of 4.6% has been fabrica ted using a high T-g hole transport polymer, a small molecule emission laye r, 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 enc apsulation, the device showed a high peak brightness of 4.4 x 10(6) cd/m(2) at 100 A/cm(2) and an efficiency of 4.4 cd/A.
