Despite over a century of research and progress, scintillation detectors remain a hot topic.
The performance of ionizing radiation detection devices has been significantly enhanced by …

Fast and high-resolution x-ray imaging demands scintillator films with negligible afterglow,
high scintillation yield, and minimized cross-talk. However, grain boundaries (GBs) are …

Low‐dimensional perovskite halides have shown a great potential as X‐ray detection
materials because of efficient exciton emissions originating from strongly spatially localized …

Low-dimensional organic–metal halides are regarded as an emerging class of X-ray
scintillation materials, but most of the discovered compounds are confronted with challenges …

All-inorganic and hybrid copper (I) halides have recently emerged as candidate optical
materials due to their extremely high light emission efficiencies, nontoxic and earth …

An ultrabright, ultrafast, and low‐cost ideal scintillator has been critically absent and is sorely
desired in scintillation detection, but has hitherto not been found. Here, a high‐quality bulk …

Cs3Cu2I5 nanocrystals (NCs) are considered to be promising materials due to their high
photoluminescence efficiency and X-ray hardness. However, the present strategy depends …

X-ray imaging based on a single gray level shows visual blind parts and affects accurate
judgment in some situations. Color-cognized x-ray imaging will boost the recognition …

Copper (I) halide perovskite Cs3Cu2I5 has recently attracted tremendous interest and has
been considered an exceptionally promising scintillator due to its high quantum yield …
