Ultra-Broad Emission Copper Halide Scintillator-Based X-Ray Imager.

ABSTRACT: Lead-free metal-halide scintillators are gaining considerable attention as more eco-friendly and superior alternatives to their lead-based counterparts. However, novel broad-emission band scintillators like the state-of-the-art CsI: Tl scintillator, which can generate high signals due to its strong compatibility with the spectral responsivity of regular photodiode arrays, are still less investigated. Herein, a TPA₂Cu₂I₄ (TPACI) copper halide scintillator with a unique ultra-broad emission (FWHM > 240 nm) is developed, which shows universal compatibility with the peak response range of commercial photodetector. The optical properties characterization and mechanism analysis indicates that this ultra-broad spectrum can be attributed to the dual self-trapped ex
