A scintillator is a special type of energy conversion material that can convert high‐energy X/gamma‐rays into visible light. These materials are indispensable parts of advanced technologies, that is, for nuclear energy, astrophysics, non‐destructive security inspection, industrial detection, and medical imaging. The emitters within the scintillators are mostly limited to bismuth, cerium, europium, thallium, lead, tungsten, etc. A shared feature of these elements is the relatively high atomic number, which is responsible for high radiation stopping power and radiation‐induced luminescence. As a new area in this field, uranyl‐bearing scintillators show intrinsic merits for designing new materials with X‐ray detection capability, that is, a large photoelectric cross‐section, high X‐ray attenuation efficiency, and high crystal density. In their Concept article on page 1900 ff., Y. Wang and S. Wang et al. discuss their work on the topic of “uranyl‐bearing scintillators” and present challenges for further development.
