Key Points

This research aims to explore how intrinsic defects and dopants affect photoluminescence in zero-dimensional zinc-based halides.
Examined the luminescence properties of Cs2ZnX4 samples with varying dopants.
Analyzed the intrinsic defect structures and their interactions with dopants to understand luminescence mechanisms.
Demonstrated that intrinsic defects significantly influence photoluminescence characteristics.
Showed a clear coupling effect between dopants and defects leading to enhanced thermochromic luminescence in the materials.

Reveals the role of intrinsic defects and dopants in photoluminescence of zinc halides, indicating potential for stable materials.

Abstract

complex responsible for thermochromic luminescence in Ag-doped systems. Ultimately, this defect-chemistry-driven model demonstrates that abundant intrinsic defects and their coupling with dopants govern the luminescence of 0D zinc-based halides, offering insights for designing high-performance, stable lead-free materials.
