Abstract Zero‐dimensional (0D) metal halides are attractive due to their structure‐dependent and tunable photoluminescence properties. Herein, a new 0D organic–inorganic hybrid Zn‐based halide, (C 4 H 12 N 2 )ZnBr , featuring long‐term stable crystal structure moisture‐stable PL emission under various extreme conditions is reported. A strong electron–phonon coupling effect enables the halide display highly efficient blue light at 472 nm with large Stokes shift of 7385 cm −1 . Intriguingly, heterovalent substitution Cu + ‐Zn 2+ further enhances quantum efficiency 60% as introduction effectively suppresses nonradiative recombination process. Besides, formation twisted [SbBr ] − tetrahedra via Sb 3+ help achieve broadband near‐infrared (NIR) (760 nm) full width half maxima (FWHM) 203 nm, enabling potential applications in night‐vision nondestructive fruit damage inspection. Detailed structural optical analyses used investigate photophysical processes different self‐trapped exciton (STE) for pristine /Sb ‐doped halides. These findings advance understanding spectral regulation mechanism initiate more exploitation luminescent emerging applications.

Abstract Achieving multiple efficient emissions from a single scintillator material is challenging. This work presents several Zn or Cd‐based halide materials with tetrahedral clusters, which show high‐efficiency, multicolor emission scintillating by co‐doping Sb 3 ⁺ and Mn 2 ⁺. In this 0D structure, can function as independent centers, producing green red bands, respectively, all photoluminescent quantum yields (PLQYs) exceeding 70% for green, yellow, emissions. Notably, Ph M‐Zn:Sb 3+ @Mn out of the above compounds exhibits PLQY values 90% three color Furthermore, it demonstrates exceptional scintillation performance under X‐ray illumination, achieving resolution 18 lp mm −1 detection limit 50.1 nGy air S⁻¹, surpassing most commercial scintillators. Additionally, cross‐ independent‐emission colors produced these varying excitations have been utilized to develop novel optical anti‐counterfeiting information storage applications high security. These advances demonstrate that significantly optimize host materials, multifunctional scintillators in variety technological applications.
