P‐108: Positive Aging Mechanisms for High‐efficiency Blue Quantum Dot Light‐emitting Diodes. Issue 1 (30th May 2018) - Ding, Wen-Cheng
Abstract : Voltage reduction (2.4 V at 2 mA/cm 2 ) and efficiency improvement (7‐times) were demonstrated in blue QLEDs by positive aging process, which came from (1) improvement of carrier injection at ZnO/QD interface and/or carrier transport in QD layer, and (2) enhancement of PLQY of QD emissive layer.
