Characterization of Cl-doped two-dimensional (PEA)₂PbBr₄ perovskite single crystals for fast neutron and gamma ray detection.

ABSTRACT: In this paper, a high-quality Cl-doped two-dimensional halide perovskite (PEA)₂Pb(Br_0.95Cl_0.05)₄ crystal was prepared using a seed-induced volatile solvent method. On optimizing the Cl^- doping concentration, we found that 5% Cl-doping results in (PEA)₂PbBr₄ with the highest optical and photon yield. Based on the Cl-doped (PEA)₂PbBr₄ single crystal, the response characterization of the (PEA)₂Pb(Br_0.95Cl_0.05)₄ crystal in the mixed field of neutrons and gamma rays (n/γ) has been verified. Using the time-of-flight method and the linear relationship between integral charge and neutron yield, it was proved that (PEA)₂Pb(Br_0.95Cl
