Manipulating Crystallization and Deprotonation Reaction through Surface Engineering of ZnO for Bright and Stable Near-Infrared Perovskite LEDs

Abstract Perovskite light-emitting diodes (LEDs) have attracted significant attention owing to their rapidly increasing external quantum efficiencies (EQEs). However, achieving bright and operationally stable perovskite LEDs remains a great challenge. Here, we reveal that the mos...

Stepped‐Dimensional 2D/3D Tin‐Based Perovskites for High‐Efficiency Light‐Emitting Diodes

ABSTRACT Tin (Sn)‐based perovskite near‐infrared (NIR) light‐emitting diodes (LEDs) show great potential for applications in night vision, biomedical sensing, and optical communications. However, their performance remains limited by uncontrolled crystallization and the facile oxi...
