One-dimensional hybrid copper halides with high-efficiency photoluminescence as scintillator.

A new one-dimensional hybrid [APCHA]Cu 2 I 4 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.
