CaAl₂Si₂O₈: Tb³⁺ 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.
