Ultra‐bright, ultra‐fast, and low‐cost ideal scintillator has been critically absent and sorely desired in scintillation detection and has hitherto not been found. Here, we report a high‐quality bulk Cs3Cu2I5:Mn single‐crystal scintillator with ultra‐high light yield (∼95,772 photons/MeV, 137Cs γ‐ray), excellent energy resolution (3.79%, 662 KeV), and ultra‐fast scintillation decay time (3 ns, 81.5%). In mechanism, we find that the micro‐doping of heterovalent magnetic ions (at the ppm level) can effectively modulate the luminescence kinetics of self‐capture excitons in the scintillator. Compared with previous reports, the introduction of trace amounts of magnetic Mn2+ (∼18.6 ppm) in Cs3Cu2I5 single‐crystal shortens the scintillation decay time by several hundred times, transforming slow decay into ultra‐fast decay. Simultaneously, the light yield is also increased about three times to the highest value so far. From the comprehensive performance of the micro‐doped Cs3Cu2I5:Mn single‐crystal, these excellent scintillation properties, physical characteristics suitable for practical applications, and low‐cost advantages render this single‐crystal an ideal scintillator with great potential for commercialization.This article is protected by copyright.
