High Efficiency and Long Lifetime Quantum-Dot Light-Emitting Diodes for Flat Panel Display Applications

摘要

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.
