Thermal stability of quantum dots (QDs) and thermal management of QD light-emitting diodes (QLEDs) could significantly affect the performance, especially the efficiency roll-off behaviors of QLEDs. With effective thermal management, the efficiency roll-off is significantly suppressed and consequently our developed green QLEDs exhibit an unprecedented high brightness of over 106 cd/m2 at a current density of J=3500 mA/cm2 and a external quantum efficiency of ~10%, which is an order of magnitude higher than that of all reported QLEDs.
