A designed material with large birefringence and remarkable deep-ultraviolet transparency, KF·B(OH)3, has been discovered. The well-aligned [F·B(OH)3]- layers endow a very large bandgap (7.63 eV), comparably large birefringence (0.114 @1064 nm), and the reinforced interlayer bonding of ca. 2.16 × KBe2BO3F2.
