Abstrakt: This study presents a multi-mode X-ray detection and imaging strategy by integrating photochromism, photoluminescence, and radioluminescence into Tb 3+ -doped CaAl 2 Si 2 O 8 . CaAl 2 Si 2 O 8 : Tb 3+ 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 CaAl 2 Si 2 O 8 : Tb 3+ 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.
