High-performance, eco-friendly heavy metal-free (HMF) quantum dot LEDs are vital for next-gen displays. ZnSeTe/ZnSe/ZnS blue QDs achieve adjustable energy levels & emission peaks, yielding a peak CE of 11.8 cd A−1. Optimizing chroma efficiency, these QLEDs offer 2.2x improvement over control devices.

SETFOS simulation software was utilized to assist in determining the optimal optical structure of the device, and we find that the emission intensity and peak position can be better matched in ZnSe:0.0385Te/ZnSe/ZnS-based QLED.
