Název v původním jazyce

Zero-dimensional Cs3Cu2I5 perovskite single crystal as sensitive X-ray and γ-ray scintillator

Popis výsledku v původním jazyce

Low-dimensional halide perovskites with highly efficient luminescent properties have attracted huge attention in optoelectronic and radiation detection applications in recent years. Herein, a highly efficient 0D Cs3Cu2I5 perovskite crystal is presented for X-ray and γ-ray detection that can be easily grown from the melt by the Bridgman method. The crystal structure of Cs3Cu2I5 belongs to an orthorhombic system with a space group of Pnma. The Cs3Cu2I5 crystal is nonhygroscopic and self-absorption free due to a large Stokes shift of 120 nm originated from its self-trapped exciton emission. Its scintillation emission centers at 440 nm with a principal decay time of 967 ns. The Cs3Cu2I5 crystal not only demonstrates a high scintillation yield of about 32 000 photons per MeV and an extremely low afterglow of 0.03% at 10 ms under X-ray radiation and a high light yield of 29 000 photons per MeV with an excellent energy resolution of 3.4% at 662 keV under γ-ray radiation.
