Manipulation of X‐Ray Persistent Radioluminescence in Core–Shell–Shell Nanoparticles for Energy‐Discriminated Chromatic 3D Imaging

Lanthanide-doped fluoride nanoparticles with tunable persistent radioluminescence (persistent RL) have emerged as promising scintillators for 3D X-ray delay imaging. However, its core challenges persist in developing a highly-discriminative imaging detection technologies for complex structures composed of materials with similar density. Here, a persistent RL-assisted energy-discriminated approach is developed to realize high-resolution chromatic X-ray 3D imaging for visualizing material specific
