Abstract

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.
