摘要

短波非线性光学晶体（NLO）可以将特定波长的光转换为紫外和深紫外区域。迄今为止，大多数商业化的紫外和深紫外NLO材料都是硼酸盐晶体。硼硅酸盐结合了硼酸盐和硅酸盐的优点，具有结构类型丰富、二次谐波响应适中、紫外线透过率高等独特优势。本文总结了已知的NLO型硼硅酸盐，根据B-O和Si-O单元的连接方式可分为两类：(1)具有B-O - si共价键的硼硅酸盐；(2)具有孤立的B-O和Si-O单元的硼硅酸盐。讨论了这些硼硅酸盐的结构特征、SHG强度和UV截止边。最后，展望了该领域的发展前景。

Borosilicates as deep-ultraviolet transparent nonlinear optical crystals: Structural motifs, performance limits and future directions

Short-wavelength nonlinear optical (NLO) crystals can convert a specific wavelength of light to ultraviolet (UV) and deep-UV region. To date, most of the commercialized UV and deep-UV NLO materials are borate crystals. By combining the merits of borates and silicates, borosilicates exhibit some unique advantages of rich structural types, moderate second harmonic generation (SHG) response, and high UV transmittance. This paper summarizes the known NLO borosilicates which can be grouped into two types according to the linkage modes of B–O and Si–O units: (1) borosilicates with B–O–Si covalent bond, and (2) borosilicates with isolated B–O and Si–O units. The structural features, SHG intensities, and UV cutoff edges of these borosilicates are discussed. Finally, future perspectives in this field are presented.
