中科院新疆理化技术研究所潘世烈团队设计并合成了一种在非π共轭磷酸盐中具有巨大光学各向异性的优良双折射材料。相关研究成果发表在2021年9月15日出版的《德国应用化学》。

开发具有大双折射率的非π共轭磷酸盐双折射晶体是一个巨大的挑战。

该文中,研究人员基于KBe2BO3F2(KBBF)独特的二维层状结构,成功地设计和合成了两种新化合物Sn2PO4I和Sn2BO3I,保持了晶体的层状结构特征,增强了晶体的光学各向异性。特别是,Sn2PO4I的双折射大于或等于0.664@546nm,是已报道的硼酸盐和磷酸盐中最的大,甚至超过了商用双折射晶体YVO4和TiO2

该研究工作表明,在无机化合物的双折射方面取得了突破。同时,为今后探索大双折射材料提供了指导思想。

Abstract: Exploring non π-conjugated phosphate birefringent crystal with a large birefringence has been a great challenge. Herein, based on the unique two-dimensional layered structure in KBe2BO3F2 (KBBF), two new compounds, Sn2PO4I and Sn2BO3I, were designed and synthesized successfully, maintaining the layer structural feature and enhancing the optical anisotropy of crystals. Especially, the birefringence of Sn2PO4I is larger than or equal to 0.664 @546 nm, which is largest among the reported borates and phosphates, even surpassing commercial birefringent crystals YVO4 and TiO2. This work indicates that a breakthrough in birefringence of inorganic compound was achieved. Also, it provides a guiding idea for exploring large birefringence materials in the future.
