Crystal-glass phase transformation and glass recrystallization in zero-dimensional (0D) hybrid metal halides make them thriving in X-ray scintillators with the advantages of large-area fabrication and improved performance. Herein, we report three 0D hybrid copper(I) halides composed of identical organic cations and versatile self-assembly of copper-iodide anions and find that the volumes of inorganic anions groups are related to their lattice energies, which conformationally governed the thermodynamics of glass formation through lattice destabilization. A subsequent heating of glass counterparts allows the fabrication of hybrid bulk glass-ceramic via recrystallization, exhibiting outstanding X-ray scintillation performances (with a light yield of 64 000 ph MeV^–1 and a detection limit of 72.6 nGy s^–1) and high stability for real-time X-ray imaging (spatial resolution above 20 lp mm^–1). This multiphase transformation strategy of luminescence metal halide opens an exploratory way in structural design and phase engineering of large-area halide scintillator screens for X-ray imaging.

混合铜 (I) 基卤化物中的多相转变可改善 X 射线闪烁和实时成像

零维（0D）杂化金属卤化物中的晶体玻璃相变和玻璃再结晶使其在X射线闪烁体中蓬勃发展，具有大面积制造和改进性能的优势。在此，我们报道了三种由相同的有机阳离子和碘化铜阴离子的多功能自组装组成的0D杂化铜(I)卤化物，并发现无机阴离子基团的体积与其晶格能相关，晶格能在构象上控制玻璃的热力学通过晶格失稳形成。随后对玻璃对应物进行加热，允许通过再结晶制造混合块状玻璃陶瓷，表现出出色的 X 射线闪烁性能（光输出为 64 000 ph MeV ^–1，检测限为 72.6 nGy s ^–1）和高实时 X 射线成像的稳定性（空间分辨率高于 20 lp mm ^–1）。这种发光金属卤化物的多相转变策略为X射线成像用大面积卤化物闪烁体屏幕的结构设计和相工程开辟了一条探索性途径。
