Abstract

Two new selenites, K₂Zn₃Se₄O₁₂ (compound 1) and K₄Zn₃V₄Se₂O₁₉ (compound 2), have been successfully synthesized by solid-state reactions in vacuum tubes. Compound 1 consists of a three-dimensional (3D) framework with [SeO₃] triangular pyramids and [ZnO₄] tetrahedra in the monoclinic space group P2₁/c (No. 14). Compound 1′s cut-off edge is below 344 nm, based on its UV-Vis-NIR diffuse reflectance studies, and theoretical calculations indicate a birefringence of around 0.043 at 1064 nm. The two-dimensional layer of compound 2, in contrast, is made up of [SeO₃] triangular pyramids, [ZnO₄] tetrahedra, and [V₄O₁₃] tetrahedra. It crystallizes in the monoclinic space group C2/c (No. 15). Its UV-Vis-NIR diffuse reflectance studies demonstrate that the compound's cut-off edge is lower than 330 nm.

两种新型亚硒酸盐光学材料K2Zn3Se4O12和K4Zn3V4Se2O19的合成、结构和性能。

在真空管中通过固态反应成功合成了两种新的亚硒酸盐，K2Zn3Se4O12（化合物1）和K4Zn3V4Se2O19（化合物2）。化合物1由单斜空间群P21/c中具有[SeO3]三角锥和[ZnO4]四面体的三维（3D）框架组成（No.14）。基于其UV-Vis-NIR漫反射研究，化合物1的截止边缘低于344nm，并且理论计算表明在1064nm处的双折射约为0.043。相反，化合物2的二维层由[SeO3]三角锥、[ZnO4]四面体和[V4O13]四面体组成。它在单斜晶系空间群C2/c（编号15）中结晶。其UV-Vis-NIR漫反射研究表明，该化合物的截止边缘低于330 nm。
