Description:

We enhanced device performance by effectively suppressing electron leakage and improving hole injections in QR-LEDs. As a result, QR-LEDs achieved record-breaking performance metrics: EQE of 19.4%, CE of 72 cd/A, and luminance of 320,000 cd/m². These figures represent the highest recorded values for green QR-LEDs.
