Abstract

We report on organic electroluminescent devices based on Al cathode with luminous efficiency of 20 lm/W and external quantum efficiency of 4.6%. When pulsed in air at room temperature and without any encapsulation, high peak brightness of 4.4 × 106 cd/m2 and high efficiency of 4.4 cd/A are obtained. In contrast to current belief, we demonstrate that device quantum efficiency can be increased by tuning the ionization potential of the hole-transport moieties. The high efficiency and peak brightness reported here with Al cathode are encouraging for the manufacturing of stable devices and the development of electrically injected organic lasers.
