- 摘要:
- 双折射晶体可有效调制光的偏振，在偏光显微镜、光隔离器和偏振片等一系列光学器件中发挥着重要作用。 为了获得大双折射率的双折射晶体，根据结构与性能的关系，关键在于寻找具有大的微观极化率各向异性的功能基团。 目前，研究人员已经发现一系列双折射功能基团，例如， (BO 3 ) 3- 、 (CO 3 ) 2- 、 (B 3 O 6 ) 3- 、 (C 3 N 3 O 3 ) 3- 等，并构筑了相应的双折射晶体。在本综述中，将介绍我们团队关于新型功能基团及相应的新型双折射晶体的最新研究进展。论文报告的双折射晶体分为两大类，即无机双折射晶体和有机 - 无机杂化双折射晶体，讨论了这些双折射晶体的晶体结构特征、光学性能以及结构与性能的关系等。Birefringent crystals can efficiently modulate polarized light and thus play an important role in a series of opticaldevices such as polarized microscopes, optical isolators and polarizers. To obtain birefringent crystals of large birefringence,the key is to search for functional groups with large microscopic polarizability anisotropy based on structure-property relationships. At present, researchers have discovered a variety of functional groups, such as (BO 3 ) 3- , (CO 3 ) 2- , (B 3 O 6 ) 3- , and (C 3 N 3 O 3 ) 3- and further synthesized some excellent birefringent crystals. In this review, we will introduce recent research advances of our team on novel functional groups and birefringent crystals. These birefringent crystals are classified into two categories,namely, inorganic birefringent crystals and organic-inorganic hybrid birefringent crystals. In addition, their crystal structures, optical properties, and structure-property relationships are thoroughly discussed.
