Hydrogen-rich two-dimensional perovskite fast neutron scintillator material and preparation method and application thereof

The invention discloses a hydrogen-rich two-dimensional perovskite fast neutron scintillator material. The hydrogen-rich two-dimensional perovskite fast neutron scintillator material is an organic-inorganic layered perovskite material doped with metal ions; wherein the metal ions are selected from one or more of Mn < 2 + >, Li < + > and Eu < 3 + >; the general formula of the organic-inorganic layered perovskite material is (RNH3) 2PbX4 or L2An-1MnX3n + 1. The material realizes integration of fast neutron absorption and luminescence on a single compound; the material has good light yield and spatial resolution under different fast neutron energies. The invention also discloses a preparation method and application of the fast neutron scintillator material. 本发明公开了一种富氢二维钙钛矿快中子闪烁体材料，所述富氢二维钙钛矿闪烁体为掺杂有金属离子的有机-无机层状钙钛矿材料；其中，所述金属离子选自Mn2+、Li+、Eu3+中的一种或几种；所述有机-无机层状钙钛矿材料的通式为(RNH3)2PbX4或L2An-1MnX3n+1。该材料实现了快中子吸收和发光在单一化合物上的集成；该材料在不同的快中子能量下有很好的光产额和空间分辨率。本发明还公开了该快中子闪烁体材料的制备方法和应用。
