资源简介：
A new potential infrared (IR) nonlinear optical (NLO) material Bi2(IO4)(IO3)3 was synthesized by hydrothermal method. Bi2(IO4)(IO3)3 crystallizes in the chiral orthorhombic space group P212121 (No. 19) with a = 5.6831(11) Å, b = 12.394(3) Å, and c = 16.849(3) Å. It exhibits a three-dimensional framework through a combination of the IO3, IO4, BiO8, and BiO9 polyhedra and is the first noncentrosymmetric (NCS) structure containing [IO4]3– anion. Bi2(IO4)(IO3)3 has an IR cutoff wavelength of 12.3 μm and belongs to the type 1 phase-matchable class with a moderately large SHG response of 5 × KDP, which is in good agreement with the theoretical calculations.
