Abstract

We report in this wok the improvement of current efficiency (CE) roUroffi and power efficiency (PE) roll-off of QLED by shell engineering of quantum-dots (QDs). The inverted QLEDs using the green QDs (G-QDs) with optimized shell exhibited the extremely reduced CE roll-off of 9% at 10,000 cd/m² and also 10 times longer lifetime compared with the QLED with conventional G-QDs.
