氧化锌(II)或氧化镉(II)、V(2)O(5)和TeO(2)在高温下发生固态反应生成了两种新型四元化合物，即Zn(3)V(2)TeO(10)和Cd(4)V(2)Te(3)O(15)。 Zn(3)V(2)TeO(10)的结构是一个复杂的三维(3D)网络，由ZnO(5)、ZnO(6)、VO(4)和TeO(4)多面体通过共享角和边互连构成。具有非中心结构的 Cd(4)V(2)Te(3)O(15) 具有 3D 网络，其中镉碲酸盐层通过“孤立的”VO(4) 四面体和一维 (1D) 氧化钒螺旋链进一步互连。 Cd(4)V(2)Te(3)O(15)的二次谐波产生(SHG)效率约为KH(2)PO(4)(KDP)的1.4倍。这两种化合物都是直接带隙半导体，并且在0.6-10.0μm范围内是透明的。发光测量表明这两种化合物在蓝光区域表现出宽的发射带。
Solid-state reactions of zinc(II) or cadmium(II) oxide, V(2)O(5), and TeO(2) at high temperature led to two novel quaternary compounds, namely, Zn(3)V(2)TeO(10) and Cd(4)V(2)Te(3)O(15). The structure of Zn(3)V(2)TeO(10) is a complicated three-dimensional (3D) network constructed by the interconnection of ZnO(5), ZnO(6), VO(4), and TeO(4) polyhedra via corner- and edge-sharing. Cd(4)V(2)Te(3)O(15) with an acentric structure features a 3D network in which the cadmium tellurite layers are further interconnected by both "isolated" VO(4) tetrahedra and one-dimensional (1D) vanadium oxide helical chains. Cd(4)V(2)Te(3)O(15) displays a second harmonic generation (SHG) efficiency of about 1.4 times that of KH(2)PO(4) (KDP). Both compounds are direct band-gap semiconductors and are transparent in the range of 0.6-10.0 mum. Measurements of luminescence indicate that both compounds exhibit broad emission bands in the blue-light region.
