Graphical Abstract

Trading places: Two new nonlinear optical materials, α- and β-Ba2[GaF4(IO3)2](IO3) (1 and 2), were designed via three-site aliovalent substitution of VO4F2 in α- and β-Ba2[VO2F2(IO3)2](IO3) by GaO2F4. The new materials display large second-harmonic generation responses (≈6×KH2PO4 (KDP)), wide energy band gaps (4.61 and 4.35 eV), and high laser damage thresholds (29.7× and 28.3× relative to that of AgGaS2).

Abstract

Two mixed-metal gallium iodate fluorides, namely, α- and β-Ba2[GaF4(IO3)2](IO3) (1 and 2), have been designed by the aliovalent substitutions of α- and β-Ba2[VO2F2(IO3)2](IO3) (3 and 4) involving one cationic and two anionic sites. Both 1 and 2 display large second-harmonic generation responses (≈6×KH2PO4 (KDP)), large energy band gaps (4.61 and 4.35 eV), wide transmittance ranges (≈0.27–12.5 μm), and high relevant laser-induced damage thresholds (29.7× and 28.3×AgGaS2, respectively), which indicates that 1 and 2 are potential second-order nonlinear optical materials in the ultraviolet to mid-infrared. Our studies propose that three-site aliovalent substitution is a facile route for the discovery of good NLO materials.
