This study presents a multi-mode X-ray detection and imaging strategy by integrating photochromism, photoluminescence, and radioluminescence into Tb-doped CaAlSiO. CaAlSiO: Tb exhibits stable radioluminescence, oxygen vacancy-related photochromism, and photoluminescence modulation, all of which showed a linear relationship with X-ray exposure. This multi-mode response enables high-quality imaging and detection in both bright and dark conditions, facilitating time-dependent cumulative X-ray radiation dose assessments. Reversible color and luminescence changes are achieved through cyclic tests involving alternating X-ray and 473 nm laser irradiation. The PDMS CaAlSiO: Tb ink and flexible film demonstrate high suitability for wearable X-ray detection devices and imaging of irregular objects, offering an innovative approach to X-ray detection and imaging.
本研究通过将光致变色、光致发光和辐射发光集成到掺Tb的CaAlSiO中，提出了一种多模式X射线检测和成像策略。CaAlSiO:Tb表现出稳定的辐射发光、与氧空位相关的光致变色和光致发光调制，所有这些都与X射线暴露呈线性关系。这种多模式响应能够在明亮和黑暗条件下进行高质量的成像和检测，便于进行随时间变化的累积X射线辐射剂量评估。通过涉及交替X射线和473nm激光照射的循环测试实现了可逆的颜色和发光变化。聚二甲基硅氧烷（PDMS）CaAlSiO:Tb墨水和柔性薄膜对可穿戴X射线检测设备和不规则物体成像具有高度适用性，为X射线检测和成像提供了一种创新方法。
