Abstract

Environmentally friendly lead-free metal halide scintillators have attracted significant research interest in recent years in the field of radiation detection due to their low toxicity and outstanding radioluminescent properties. However, enhancing the luminescence performance of lead-free metal halide scintillators and fabricating thin films that integrate high light output, high spatial resolution, and excellent compatibility with photodetectors remain major challenges. To address these issues, this study employs Cs₃Cu₂I₅ as the scintillating material and introduces Terbium (Tb) doping to tune its emission to match current photodetectors. A high-refractive-index flexible UV-curable adhesive, NOA170F, is used as the matrix to synthesize a Cs₃Cu₂I₅: Tb scintillating thin film featuring a large Stokes shift, high luminescence intensity, low cost, environmental friendliness, and good stability. The luminescence mechanism and X-ray scintillation properties of the film are also investigated.
