Abstract

Abstract: Colloidal quantum‐dot based hybrid light‐emitting diodes (QD‐LEDs) that exhibit high efficiency, long lifetime, solution processability, color tunability and narrow emission bandwidth are reported. The devices possess maximum current and power efficiency of 3.2 cd/A and 2.1 lm/W for blue, 60 cd/A and 54 lm/W for green, and 15 cd/A and 18 lm/W for red emission. With exceptional good lifetime, the current QD‐LEDs are promising for flat panel display applications.
