Abstract: A blue organic light-emitting device that simultaneously realizes a driving voltage of 3.25 V, external quantum efficiency of 30%, and a power efficiency of 78 lm W−1 at 1000 cd m−2 is developed. By using a mixed-host system, the device shows ≈1.4 times higher power efficiency than that of the corresponding double emission layer at a high brightness.
