AgBi(SO4)(IO3)2: aliovalent substitution induces structure dimensional upgrade and second harmonic generation enhancement

AgBi(SO₄)(IO₃)₂, a Bi-containing 3D sulfate iodate with a similar favorable nonlinear optical framework and enhanced SHG effect, was designed from a 2D iodate by [SO₄]²⁻ replacing [IO₃]⁻.
