X-ray imaging has received sustained attention for healthcare diagnostics and nondestructive inspection. To develop photonic materials with tunable photophysical properties in principle accelerates radiation detection technologies. Here the rational design synthesis of doped halide perovskite CsCdCl3 :Mn2+ , R4+ (R = Ti, Zr, Hf, Sn) are reported as next generation storage phosphors, capability is greatly improved by trap management via Mn2+ site occupation manipulation heterovalent substitution. Specially, Zr4+ displays zero-thermal-quenching (TQ) radioluminescence anti-TQ X-ray-activated persistent luminescence even up to 448 K, further revealing charge-carrier compensation redeployment mechanisms. resolution 12.5 lp mm-1 demonstrated, convenient 3D curved objects realized a time-lapse manner. This work demonstrates efficient modulation energy traps achieve high capacities promote future research into flexible detectors.
