The first zinc iodate fluoride, ZnIOF, was synthesized by the Zn cation, the IO group, and fluorine ion, where Zn is coordinated by O atoms from iodate and F atoms to form the ZnOF polyhedron. It has outstanding optical characteristics, including large birefringence (Δ = 0.219 at 546 nm), wide band gap ( = 4.2 eV), and good thermal stability (over 475 °C), showing a subtle balance between the wide band gap and birefringence.
首个碘酸锌氟化物ZnIOF由锌阳离子、IO基团和氟离子合成，其中锌由碘酸盐中的氧原子和氟原子配位，形成ZnOF多面体。它具有出色的光学特性，包括大双折射（546 nm处Δ = 0.219）、宽带隙（ = 4.2 eV）和良好的热稳定性（超过475°C），在宽带隙和双折射之间展现出微妙的平衡。
