High Color Purity Lead‐Free Perovskite Light‐Emitting Diodes via Sn Stabilization

Abstract Perovskite‐based light‐emitting diodes (PeLEDs) are now approaching the upper limits of external quantum efficiency (EQE); however, their application is currently limited by reliance on lead and by inadequate color purity. The Rec. 2020 requires Commission Internationale de l'Eclairage...
