Neutron radiation fields frequently coexist with γ-rays, posing a significant challenge to ensure the accuracy of neutron detection. 2D perovskites have been proved to be the potential fast neutron scintillators due to their structural properties and excellent luminescent performance. Herein, the study reports on the scintillation properties of 2D perovskite phenethylammonium lead bromide ((PEA)PbBr) single crystal (SC) induced by different types of radiation and first demonstrate its pulse shape discrimination (PSD) capability in neutron/gamma (n/γ) mixed radiation fields.
