Rb3B5O8F2 and K0.6Rb2.4B5O8F2: two new deep-ultraviolet transparent nonlinear optical fluorooxoborates designed by cation regulation

Two new fluorooxoborates, Rb3B5O8F2 and K0.6Rb2.4B5O8F2, were successfully obtained by cation regulation. Both of them crystallize in a non-centrosymmetric space group P21. The structural evolution from Li2Na0.9K0.1B5O8F2 to Rb3B5O8F2, as well as the structural comparison between RbB5O8 and Rb3B5O8F...

Description
Summary:Two new fluorooxoborates, Rb3B5O8F2 and K0.6Rb2.4B5O8F2, were successfully obtained by cation regulation. Both of them crystallize in a non-centrosymmetric space group P21. The structural evolution from Li2Na0.9K0.1B5O8F2 to Rb3B5O8F2, as well as the structural comparison between RbB5O8 and Rb3B5O8F2, is discussed in detail. The linear optical and nonlinear optical properties were measured. Furthermore, the structure–property relationships of the alkali metal fluorooxoborates were determined by theoretical calculations.
