A new barium fluorooxoborate, BaB5O8F·xH2O (x ≈ 0.17), with two interesting independent three-dimensional B-O/F frameworks has been synthesized by a solid-state reaction in a closed system. Compared with the lead fluorooxoborate PbB5O8F, BaB5O8F·xH2O exhibits a comparable birefringence and a wider UV transparency window.

The design of new materials with special performances is still a great challenge, especially for the deep-ultraviolet nonlinear optical materials in which it is difficult to balance large bandgaps and strong second harmonic generation responses due to their inverse relationship. Cation variation not only influences the whole structure frameworks but also directly participates in the formation of electronic structures, both of which could lead to the uncontrollability of the properties of the designed materials. Here, a novel approach, aiming at purposeful and foreseeable material designs, is proposed to characterize the role of cations.

Substitution of oxygen by fluorine in the borate group offers a materials platform from which intriguing structure and functionality may arise. Herein, we report a new fluorooxoborate, BaB O F , synthesized by introducing the F atoms into the BaO-B O system. BaB O F exhibits a unique oxyfluoride layer [B O F] and a deep-ultraviolet cutoff edge below 180 nm.
