Metal-free scintillators excite X-ray community

Nature Photonics volume 15, pages 171–172 (2021)Cite this article

Subjects

Scintillators used in X-ray detectors typically require the use of heavy metal atoms to efficiently harvest ionizing radiation. Now the use of halogens is shown to yield efficient, metal-free organic scintillators.
