A material with a large birefringence is needed for optical systems, and borate is a good choice as an excellent birefringent material. Herein, we report two borates BaM^IV(BO₃)₂ (M^IV = Ti, Sn), in which the [TiO₆] and [SnO₆] units have similar coordination environments. Moreover, the experimental birefringence of BaTi(BO₃)₂ is equal to or larger than 0.169 at 546 nm measured by using a polarizing microscope, which mainly originates from the high-density and parallel arrangement of the isolated [BO₃] groups. This discovery indicates that BaTi(BO₃)₂ can be a promising ultraviolet birefringent material.

BaTi（BO3）2：一种极好的双折射材料，具有高度共面的分离的[BO3]基团

光学系统需要具有双折射大的材料，并且硼酸盐作为优良的双折射材料是一个很好的选择。在这里，我们报告了两个硼酸钡BaM ^IV（BO ₃）₂（M ^IV = Ti，Sn），其中[TiO ₆ ]和[SnO ₆ ]单元具有相似的配位环境。此外，使用偏光显微镜测得的BaTi（BO ₃）₂在546 nm处的实验双折射等于或大于0.169，这主要源于分离的[BO ₃ ]基团的高密度和平行排列。该发现表明BaTi（BO ₃）₂ 可以是有前途的紫外线双折射材料。
