Scintillation-based X-ray detection has been widely used in various fields from medical diagnostics to security. In this study, we report four new CuI–based hybrid materials consisting of anionic inorganic chains coordinated to cationic ligands. Due to their unique bonding nature, these compounds demonstrate high stability, solution-processability, and efficient photoluminescence with PLQYs reaching ~85%. Their X-ray scintillation properties are characteristic of high light yield comparable to commercially available scintillators, excellent linear response to X-ray dose rate, low detection limit and radio-robustness. In addition, the emission mechanisms and structure–property relationships are also analyzed using both experimental and theoretical methods. These findings suggest possibilities for developing new and high-performance CuI–based hybrid materials for efficient radiation detection and imaging.
