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...

Coordination-mediated cold quenching for the synthesis of strongly quantum-confined FAPbI3 quantum dots

Strong quantum confinement can fundamentally reshape excitonic processes and radiative recombination in perovskite quantum dots (QDs), yet accessing this regime remains challenging in organic-inorganic hybrid FAPbI3 nanocrystals because of their low crystallization barrier and ra...

Halogen Substitution as a “Chirality Editor” for Amplifying Spin‐Selective Transport in Lead‐Free Metal‐Halide Hybrids

ABSTRACT Lead‐free metal‐halide hybrids hold promise as flexible semiconductors for X‐ray detection, but their application is constrained by inefficient carrier transport. Here, we introduce halogen substitution on chiral molecular cations as a “chirality editor” to modulate the...
