Description
Tao Yang and co-authors tame efficiency roll-off in near-infrared light emitters in a 2026 study. Perovskite quantum dot LEDs promise bright infrared light, but their efficiency sags badly at high power. The fix until now traded surface health for better charge flow.
The team added an ionic liquid to the washing solvent during dot preparation. It suppressed defect formation and wrapped each dot in a protective layer at once. Treated films showed half the trap density and ten times the conductivity of untreated ones. Finished devices hit a record efficiency near twenty-five percent and held about twenty percent at high output, the gentlest roll-off yet reported. Large-area versions lit bioimaging and encryption demos.
