Heterovalent Cd2+-Doped Cs3Cu2I5 Scintillators with Modulated Exciton-Phonon Coupling for High-Resolution X-ray Imaging.
Zero-dimensional (0D) copper-based halides have demonstrated significant potential in the field of high-performance X-ray detection owing to their exceptional optical properties, low toxicity, and structural stability. However, their photoluminescence (PL) efficiency and imaging resolution are limited by intrinsic defe...
