Herein, we report a nontoxic copper-halide scintillator featuring an organic framework structure, where hydrophobic long-chain molecules impart exceptional waterproof properties to the scintillator even after being soaked in water for 500 days. Moreover, a flexible film achieved from the stable scintillator demonstrates remarkable radiation robustness along with a high spatial resolution of 16.6 lp mm<sup>−1</sup> and a low limit of detection of 33.75 nGy<sub>air</sub> s<sup>−1</sup>. Finally, leveraging color and spatial reconfiguration technologies enables impressive 3D X-ray imaging, revealing clear and distinct internal details of objects.

This method utilizes aggregation-induced emission luminogens to track reactive oxygen species (ROS), offering a non-invasive assessment of pea responses to stress. Fluorescence intensity monitored during seed germination (spanning several days) negatively correlated with both stress resistance and growth potential while being positively associated with ROS metabolic gene expression, suggesting that reduced fluorescence reflects enhanced stress adaptation through ROS-mediated pathways.
