Abstract Scintillators, which can convert high‐energy ionizing radiation (e.g., X‐ or γ ‐rays) into ultraviolet‐visible light, have been widely applied in medical and industrial fields. Developing new scintillation materials with high performance low cost is very desirable order to address the growing application demands. Among them, single‐crystal scintillators of organic‐inorganic hybrid metal halides (OIMHs) attracted much attention because their excellent optical transparency, suppressed light scattering, facile solution preparation methods.

Notably, for any scintillator, two fundamental issues arise: Which kind material suitable what form should exist? answer former question involves sequence certain atoms into specific crystal that facilitate conversion X-ray light, whereas latter assembling these crystallites particular forms can guide light propagation toward its corresponding pixel detector. Despite their equal importance, efforts are overwhelmingly devoted improving X-ray-to-light conversion, while material-form-associated propagation, which determines optical signal collected imaging, largely overlooked.
