We report quantum dot light-emitting diodes (QD-LEDs) whose emitting layers are composed of InP-based QDs and an organic electron-transporting material (ETM). We demonstrated green QD-LEDs with a high maximum external quantum efficiency of 10% and a low driving voltage. In addition, the origin of the high performance was investigated.
