Phase stabilization via A-site ion anchoring for ultra-stable perovskite light emitting diodes

Abstract

A novel ion anchoring strategy stabilizes the perovskite phase, yielding ambient stable perovskite films and ultra-stable perovskite light-emitting diodes (PeLEDs) with an unprecedented operational half-lifetime over 37.2 years at 100 cd m−2 and exceeding 27% efficiency, marking a new stability benchmark for next-generation display and lighting applications.
