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.

Direct Fast-Neutron Detection by 2D Perovskite Semiconductor.

Fast-neutrons play a critical role in a range of applications, including medical imaging, therapy, and nondestructive inspection. However, direct detecting fast-neutrons by semiconductors has proven to be challenging due to their weak interaction with most matter and the requirement of high carrier mobility-lifetime (µτ) product for efficient charge collection. Herein, a novel approach is presented to direct fast-neutron detection using 2D Dion-Jacobson perovskite semiconductor BDAPbBr .
