Abstract Zero‐dimensional (0D) structure‐based manganese metal halides (MHs) are believed to be the most promising candidates for next‐generation X‐ray scintillators due their intense radioluminescence and environmental friendliness. However, low‐temperature (<180 °C), large‐area integration with more efficient detection remains a tremendous challenge. Herein, from perspective of cation (ionic liquids) structure design, basic physical parameters 0D MHs regulated. And calculations experimental results demonstrate larger‐size cations that induce lower melting temperatures, larger exciton‐binding energies, ion migration energy, tunable hardness, which desirable MHscintillators. As result, champion materialHTP 2 MnBr 4 is achieved as glassy transparency wafer by (165 °C) melt‐quenching.
