AbstractLow-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 Cs(3)Cu(2)I(5)perovskite crystal is presented for X-ray and gamma-ray detection that can be easily grown from the melt by the Bridgman method. The crystal structure of Cs(3)Cu(2)I(5)belongs to an orthorhombic system with a space group ofPnma. The Cs(3)Cu(2)I(5)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 Cs(3)Cu(2)I(5)crystal not only demonstrates a high scintillation yield of about 32 000 photons MeV(-1)and an extremely low afterglow of 0.03% at 10 ms under X-ray radiation, but also possesses a high light yield of 29 000 photons MeV(-1)with an excellent energy resolution of 3.4% at 662 keV under gamma-ray radiation.
