Transparent Solid‐State Lithiated Neutron Scintillators Based on Self‐Assembly of Polystyrene‐block‐poly(ethylene oxide) Copolymer Architectures

A new transparent neutron-scintillating material has been developed based on polystyrene-block-poly(ethylene oxide). The unique self-assembly structure of the block copolymer makes it possible to dope hydrophilic Li+ in the ethylene-oxide domain and hydrophobic organic fluors in the styrene domain (see Figure).
