Abstract
AbstractA novel noncentrosymmetric (NCS) polar fluoride sulfate, CsSbF2SO4, was obtained by ionothermal synthesis. A meticulously designed co‐substitution approach was used to successfully replace the [TiO6]8− and [PO4]3− functional groups in KTiOPO4 (KTP) with [SbO4F2]7− and [SO4]2− units, respectively. The structure of CsSbF2SO4 features a pseudo‐3D framework consisting of interconnected 1D [SbF2O2SO4]5− chains of corner‐sharing [SbO4F2]7− octahedra and [SO4]2− tetrahedra. The title compound exhibits a sharply enlarged band gap compared to its parent compound, KTP, benefitting from the introduction of F− ions and the displacement of Sb3+ cations. Second harmonic generation (SHG) measurements manifested that CsSbF2SO4 is phase‐matchable and revealed a strong SHG response of about 3.0 KH2PO4 (KDP), which is the highest value reported for any metal sulfate reported to date. The reported fluoride sulfate is a promising near ultraviolet (UV) nonlinear optical (NLO) material.
