Nonlinear optical (NLO) crystal materials play an important role in modern laser science and technology. BO3 planar primitives are used as excellent non-linear optical building blocks to design and synthesize a series of excellent nonlinear optical crystal materials. NO3 is also recognized as one of the ideal structural units for constructing NLO materials due to its conjugate planar structure . However, nitrate is very soluble in water, which makes it a bottleneck to develop this kind of compound as an NLO crystal material. Chinese Academy of Sciences, Institute of Materials Science and Structure Research, State Key Laboratory of Structural Chemistry Luo Junhua led by inorganic photovoltaic functional crystal materials research team, the National Outstanding Youth Fund, Chinese Academy of Sciences strategic pilot project of science and technology and Hercynian "team hundred" plan selected Zhao Funded by the National Natural Science Foundation of China and the three funds sponsored by the National Natural Science Foundation of China and the "Chunmiao Talents" project of the Hercynian Research Institute of the Chinese Academy of Sciences and the Outstanding Youth Fund of Fujian Province, a new type of nitric acid Salt NLO material Bi3TeO6OH (NO3) 2. Due to the synergetic effect of the three kinds of elements, the frequency doubling effect has reached 3 times KDP. At the same time, experiments show that the material has high water resistance, and collaborates with Lin Zhe-shu, a researcher at the Institute of Physics and Chemistry, Chinese Academy of Sciences, and initially explained by theoretical calculations The reason of its water resistance. This study shows that multifunctional cell complex is an effective method for the development of nitrate NLO materials with high water resistance and large octave effect. The research results are published in Angew. Chem. Int. Ed., 2016, DOI: 10.1002 / anie.201609876). Recently, the team also found a novel non-beryllium deep-UV phosphate NLO crystalline material, Cs2LiPO4, whose monolayer has a honeycomb-like topological structure that allows its octave effect to reach the phosphate NLO The highest 1.8x KDP crystal material. In cooperation with Lin Zhe-Shuai, Institute of Physics and Chemistry, Chinese Academy of Sciences, the generation mechanism of frequency doubling effect has been revealed theoretically, which provides a useful reference for the development of related materials. The findings were published in Chem. Mater., 2016, 28, 7110 & # 8722; 7116. PhD student Shen Yaoguo was the first author of the paper. Previously, the team has made a series of research advances in the non-beryllium deep-UV NLO materials. Relevant results have been published in Nat. Commun. (2014, 5, 4019); J. Am. Chem. Soc., 2014, 136, 8560-8563 (2015, 137, 2207-2210); Angew. Chem. Int. Ed. (2015, 54, 4217-4221); J. Am. Chem. Soc. , 2961-2964) and the like.
