Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

open access: yesAdvanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.
