Prediction of New Functional Fluorooxoborates with Expected Anionic Framework: A Case of CaB3O5F
-
Abstract
The prediction of new fluorooxoborates as ultraviolet (UV)/deep ultraviolet (DUV) opto-electronic functional materials from a largely unexplored chemical space is a challenging task. It has been suggested that the anionic frameworks formed by B-O and B-O-F units significantly determine the physical properties of fluorooxoborates. Therefore, the rational design of anionic frameworks could facilitate the materials discovery process. Herein, we propose that a candidate anionic framework can be efficiently derived from an existing one by slightly altering its oxygen content. Following this idea, we hypothesized the existence of a 1D B_3O_5F_\infty chain from the well-known 2D B_6O_9F_2_\infty layer. Accordingly, seven CaB_3O_5F structures with the expected anionic framework were successfully predicted. First-principles calculations show that all these structures have potential in the UV/DUV birefringent or nonlinear optical (NLO) material field, indicating that the 1D B_3O_5F_\infty chain is indeed a promising anionic framework for achieving UV/DUV birefringent and NLO performance.
