摘要：

Solid-state reactions of zinc(II) or cadmium(II) oxide, V2O5, and TeO2 at high temperature led to two novel quaternary compounds, namely, Zn3V2TeO10 and Cd4V2Te3O15. The structure of Zn3V2TeO10 is a complicated three-dimensional (313) network constructed by the interconnection of ZnO5, ZnO6, VO4, and TeO4 polyhedra via corner- and edge-sharing. Cd4V2Te3O15 with an acentric structure features a 3D network in which the cadmium tellurite layers are further interconnected by both "isolated" VO4 tetrahedra and one-dimensional (1D) vanadium oxide helical chains. Cd4V2Te3O15 displays a second harmonic generation (SHG) efficiency of about 1.4 times that of KH2PO4 (KDP). Both compounds are direct band-gap semiconductors and are transparent in the range of 0.6-10.0 mu m. Measurements of luminescence indicate that both compounds exhibit broad emission bands in the blue-light region.
