ABSTRACT

Zou and co-workers' work demonstrates that multisite fine-tuning is an effective strategy for modifying the emissions of hybrid metal halide. Through systematic chemical composition engineering, they successfully discover a unique multicolor phosphor [BPy]2CdX4:xSb3+, which achieves a wide range of tunable emissions within a single-component material. Furthermore, the characteristic of rich emission color covering a wide spectral range from blue to near-infrared identifies [BPy]2CdX4:xSb3+ as a promising luminescent material for high-security anti-counterfeiting applications. Zou and co-workers provide valuable insights into the design of new hybrid metal halide luminescent materials with tunable emissions, and their discovery is scientifically interesting.
