 academy fujian WuGouSuo progress in the study of nonlinear optical crystal materials

takeaway: nonlinear optics ( NLO) Crystal material in modern laser science and technology plays an important role. BO3 graphic primitives as excellent nonlinear optical build primitives are used to design and synthesis of a series of excellent nonlinear optical crystal materials, NO3 - due to its conjugate planar structures has also been recognized as one is to construct the ideal structural unit of NLO materials.

nonlinear optics ( NLO) Crystal material in modern laser science and technology plays an important role. BO3 graphic primitives as excellent nonlinear optical build primitives are used to design and synthesis of a series of excellent nonlinear optical crystal materials, NO3 - due to its conjugate planar structures has also been recognized as one is to construct the ideal structural unit of NLO materials. Nitrate, however, due to very easily soluble in water, making such compounds as NLO crystal material development bottleneck.

structure of Chinese Academy of Sciences, fujian material research institute researcher at the state key laboratory of structural chemistry Luo Junhua led by inorganic photoelectric functional crystal materials research group, the national outstanding youth fund, strategic leader of the Chinese Academy of Sciences institute of science and technology projects and hercynian 'team' one hundred people plan list zhao three host and youth fund of national natural science foundation surface and the hercynian research institute of Chinese Academy of Sciences special talent of 'green shoots' and the fujian province outstanding youth fund projects such as funding, a successful contains three function structure of the primitive new nitrate NLO materials Bi3TeO6OH ( 3号) 2. Due to the synergy of three kinds of primitive, its frequency doubling effect three times the KDP; At the same time, the results show that the material has a high water resistance, and the technical institute of physics and chemistry of the Chinese Academy of Sciences researcher Lin Zheshuai cooperation, through the theoretical calculation of preliminary explain its water resistance. The research shows that multifunctional composite is a kind of primitive development with high water and large frequency doubling effect nitrate NLO materials, the results of the study, published in the German applied chemistry ( Angew。 化学。 Int。 艾德。 ,2016 DOI: 10。 1002/anie. 201609876). On.

recently, the team also found a new type of beryllium Cs2LiPO4 deep uv phosphate NLO crystal materials, its single has a kind of cellular topology structure, make its frequency doubling effect achieved through such deep ultraviolet band of phosphate NLO crystal materials among the highest in 1. Eight times KDP. Lin Zheshuai cooperation with physics and chemistry of the Chinese Academy of Sciences in theory reveals the mechanism of the effect of frequency doubling, provides a useful reference for the development of related materials. The results of the study, published in the chemical material ( 化学。 Mater. , 2016, 28, 7110 & # 8722; 7116). The first author, a doctoral candidate Shen Yaoguo for paper.

after the team in the absence of beryllium deep uv NLO materials research progress in series, the results are described in Nat. Commun. ( 2014, 5401, 9) ; J。 点。 化学。 Soc。 ( 2014, 136, 8560 - 8563). ; J。 点。 化学。 Soc。 ( 2015, 137, 2207 - 2210). ; Angew。 化学。 Int。 艾德。 ( 2015, 54, 4217 - 4221). ; J。 点。 化学。 Soc。 ( 2016, 138, 2961 - 2964). And so on.
