摘要

A novel quaternary borate, Na2.18K0.82SrB 5O10, has been prepared by high-temperature solution reaction below 800 °C. Single-crystal XRD analyses showed that it crystallizes in the triclinic P1? with a = 7.3900(15) ?, b = 7.6490(15) ?, c = 9.773(2) ?, α = 79.31(2)°, β = 70.85(2)°, γ = 62.09(1)°, Z = 2. The basic structural unit in Na2.18K0.82SrB5O10 is a double ring [B5O10]5- composed of one BO4 tetrahedron and four BO3 triangles. The [B5O 10]5- groups are arranged around crystallographic centers of symmetry to form [B10O20]10- columns that are held together by Na+, K+/Na+, and Sr 2+ cations via electrostatic interactions. The IR spectrum further confirmed the presence of both BO3 and BO4 groups. UV-vis diffuse reflectance spectrum showed a band gap of about 3.80 eV. Solid-state fluorescence spectrum exhibited the maximum emission peak at around 337.6 nm.

NA2.18K0.82SRB5O10中的基本结构单元是双环[B5O10] 5-由一个BO4四面体和四个BO3三角形组成。 [B5010] 5-基团围绕晶体摄像中心布置，以通过静电相互作用通过Na +，K + / Na +和Sr 2+阳离子在一起形成[B10O20] 10塔。 IR光谱进一步证实了BO3和BO4组的存在。 UV-Vis漫反射谱显示出约3.80eV的带隙。 固态荧光光谱在约337.6nm左右显示出最大排放峰。
