Highly efficient polymer white-light-emitting devices with a single emission layer containing a sky–blue triplet emitter and some home-made yellow phosphorescent iridium complexes doped into a polymer host are fabricated. The optimized devices present CIE coordinates of (0.395,0.452) at a current density of 12 mA cm−2.
