Abstract

A new one-dimensional hybrid [APCHA]Cu₂I₄ was designed and applied as an X-ray scintillator. It exhibits broad-band green emission with a high PLQY of 74.80% and excellent stability. It demonstrates radioluminescence property with a light yield of 28 336 photons MeV^-1, detection limit of 41 nGy_air s^-1, and high spatial limit of 13.95 lp mm^-1 in X-ray imaging.
