Although the performance of quantum-dot (QD) based light-emitting diodes (QLEDs) has been improved so far, mechanisms related to the dynamics of charges and excitons in the QD layer of QLEDs in electrical operation are still unclear. Here we investigated their dynamics based on time-resolved techniques to reveal the specific mechanisms.
