Popis:	In this paper, by using the unique properties of the efficient red-emitting Osmium (Os) complex in combination with an efficient blue-emitting Iridium (Ir) complex, we report WOLEDs with forward viewing efficiencies up to (17% photon/electron, 36 cd/A, 28 lm/W) and total peak external efficiencies up to (28.8 %, 47.5 lm/W). Results show that the Os complex is a multi-functional material that could be useful for implementing highly efficient and color-stable phosphorescent OLEDs.
