Traditional scintillators rely on rigid inorganic matrices with high- elements, whose mechanical inflexibility restricts applications in multiple scenarios. Developing an efficient scintillator that combines inorganic properties with flexibility is a desirable yet highly challenging goal. We pioneered an inorganic metafabric scintillator paradigm through self-sustained slip system engineering, transforming brittle all-inorganic scintillation materials into ductile textile architectures, yielding intrinsically conformally flexible scintillators that adhere seamlessly to complex, curved surfaces. The ultimate all-inorganic scintillator delivers near-unity quantum yield, with scintillation output more than 10 times higher than that of previous polymer matrix-based flexible scintillators. Using these metafabric scintillators, a multimodal x-ray interactive wearable platform (X-Wear) was developed, and their applications in body-centered flexible detection and imaging, mobile health, visual radiation monitoring, and breathable radiation shielding were successfully demonstrated. This work offers a previously undefined paradigm for a scintillator system design strategy that maintains the high performance of inorganic scintillators while adding the functionality of being conformally flexible and wearable of fabrics.
传统闪烁体依赖于含有高原子序数元素的刚性无机基质，其机械刚性限制了在多种场景中的应用。开发一种将无机特性与柔韧性相结合的高效闪烁体是一个理想但极具挑战性的目标。我们通过自持滑移系统工程开创了一种无机超材料闪烁体范式，将脆性全无机闪烁材料转变为韧性纺织结构，产生了本质上共形柔性的闪烁体，可无缝贴合复杂的曲面。这种终极全无机闪烁体具有近乎单位的量子产率，其闪烁输出比以前基于聚合物基质的柔性闪烁体高出10倍以上。利用这些超材料闪烁体，开发了一种多模态X射线交互式可穿戴平台（X-Wear），并成功展示了它们在以身体为中心的柔性检测与成像、移动健康、视觉辐射监测和透气辐射屏蔽方面的应用。这项工作为闪烁体系统设计策略提供了一种前所未有的范式，在保持无机闪烁体高性能的同时，增加了织物共形柔性和可穿戴的功能。
