Abstract: We report the radioluminescent properties of the recently discovered hybrid bromocuprate (MeNH₃)₂CuBr₃ in a poly(methyl methacrylate) matrix in the form of solution- produced composite thick films. The obtained films demonstrate bright turquoise photoluminescence in UV light and intense radioluminescence due to CuKα and AgKα radiation at room temperature, exceeding the radioluminescence intensity of Cs₄PbBr₆@CsPbBr₃ films by more than an order of magnitude.

Keywords: hybrid copper halides, bromocuprate, scintillator, radioluminescence, photoluminescence, X-ray imaging.
