A new noncentrosymmetric iron-iodate-fluoride Ba₂[FeF₄(IO₃)₂]IO₃ was ingeniously obtained based on the centrosymmetric Ba[FeF₄(IO₃)] through chemical tailoring. Ba₂[FeF₄(IO₃)₂]IO₃ exhibits a strong phase-matchable second-harmonic generation effect, a large band gap, and a wide mid-infrared transparent window. The chemical tailoring design based on oxide-fluoride anions affords a feasible approach to design nonlinear optical materials.

Ba2[FeF4(IO3)2]IO3：一种通过化学剪裁诱导结构演化实现的有前途的非线性光学材料

基于中心对称的Ba[FeF ₄ (IO ₃ )]，通过化学剪裁，巧妙地获得了一种新的非中心对称的碘酸铁氟化物Ba ₂ [FeF ₄ (IO ₃ ) ₂ ]IO ₃。Ba ₂ [FeF ₄ (IO ₃ ) ₂ ]IO ₃具有很强的相位匹配二次谐波产生效应、大的带隙和宽的中红外透明窗口。基于氧化物-氟化物阴离子的化学剪裁设计为设计非线性光学材料提供了一种可行的方法。
