High Spatial Resolution Perovskite Fast Neutron Imaging Screen by Cl (n, p) Nuclear Reaction.

Fast neutron imaging has emerged as a highly adaptable non-destructive inspection tool in industrial applications and scientific research. This technique predominantly employs hydrogen-rich scintillation screens based on the principle of nuclear recoil; however, it suffers from limited spatial resolution due to significant energy diffusion of recoil protons. Herein, a 1D perovskite, CsCuClI is demonstrated, for fast neutron imaging based on Cl (n,p) nuclear reaction.
