An organic light-emitting device (OLED) with enhanced efficiency by employing an ambipolar material, 2-methyl-9,10-di(2-naphthyl)anthracene (MADN) as both hole-transport and electron-transport layers has been developed. The efficiency of the device is more than 40% enhanced compared with a control device. Moreover, the operational stability, is also greatly improved as it minimizes the formation of all unstable redox species of Alq(3)(+) as well as NPB-.
