Problems solved by technology

[0003] The traditional iodate is mostly obtained under the condition of hydrothermal reaction. The presence of water dilutes the concentration of iodate in the reactant, which is not conducive to the polymerization of iodate, and even the polymerized iodate can be hydrolyzed into isolated iodate. making the discovery of polymeric iodates very difficult

Description

technical field [0001] The invention relates to the technical field of nonlinear optical crystal materials, in particular to a preparation method and application of a nonlinear optical crystal cesium iodate molybdate. Background technique [0002] Nonlinear optical crystals are key basic materials in the optoelectronic industry, which has attracted extensive attention from academia and technology. iodate because I 5+ The cation has active lone pair electrons, which can effectively improve the nonlinear optical effect, which makes researchers have great interest in it. At present, α-LiIO 3 and α-HIO 3 Already used as a commercial nonlinear optical crystal. When researchers studied iodate, they found that iodate can undergo polymerization, which effectively increased the density of iodate of nonlinear optically active groups. Previous studies have shown that polyiodate exhibits Strong nonlinear optical performance; [0003] Most of traditional iodates are obtained under t...
