Abstract Self‐trapped exciton (STE) emission, typified by antimony (Sb), with broadband characteristics, represents the next generation of materials for solid‐state lighting and radiation detection. However, little is known about multiexciton behavior Sb emission center. Here, we proposed a general approach designing antimony‐centered multi‐exciton emitting through self‐assembly. Benefitting from controllable behavior, dual‐band white light spanning entire visible spectrum was achieved. Relying on reduction an effective atomic number brought self‐assembly, excellent scintillation response to β‐rays attained. This study offers unprecedented insight into hybrid single/triple STE unveils new avenues single‐emitter white‐light as well radiographic testing using low‐risk sources.

Abstract Ionically bonded organic metal halide perovskite‐like luminescent materials, which incorporate cations and halides, have emerged as a versatile multicomponent material system. However, these materials still face challenges in terms of low phosphorescence quantum yields limited long persistent luminescence (LPL) colors. Herein, we present the design synthesis an intraligand charge‐transfer organic‐based material, form compact supramolecular hydrogen‐bonded framework (HOF) structure, exhibiting crystallization‐induced emission ligand, while halides unique two‐dimensional (2D) structure that displays intrinsic self‐trapped excitons (STE) under radiation UV light. Notably, hybrid is found to exhibit enhanced phosphorescent photoluminescence efficiency up 81.05% tunable LPL from cyan orange compared pristine phosphor, due structural distortion scaffolding effects 2D well well‐packed HOF structure. Optical characterizations theoretical calculations reveal charge transfer halogen ligand STE inorganic layers are responsible for LPL. Meanwhile, high‐efficiency yield attributed stronger hydrogen bond stacking bands. Thus, obtained provides potentials anti‐counterfeiting, security systems, so on.
