Structural Precision Meets Spectral Freedom ns2-ion–doped hybrid metal halides transform subtle lattice distortions into intense, broadband light, seamlessly spanning UV, visible, and near-infrared emission. This unified platform enables efficient white lighting, hidden NIR imaging, and multi-level optical security within a single crystalline framework. More details can be found in the Research Article by Yang Yu, Junsheng Chen, Ruifeng Lu, and co-workers (DOI: 10.1002/adma.202511051).
