Title: 3D hierarchical Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O and Zn{sub 3}(VO{sub 4}){sub 2} microspheres: Synthesis, characterization and photoluminescence

Abstract

Highlights: Black-Right-Pointing-Pointer 3D hierarchical microspheres of Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O were gained with glycine-assisted hydrothermal method. Black-Right-Pointing-Pointer Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O can be transformed into Zn{sub 3}(VO{sub 4}){sub 2} with the similar morphologies by calcination. Black-Right-Pointing-Pointer The PL properties of Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O and Zn{sub 3}(VO{sub 4}){sub 2} were studied. -- Abstract: Via a simple glycine-assisted hydrothermal route, large-scale 3D hierarchical Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O microspheres have been fabricated. Their purity, crystalline phase, morphologies and thermal stability were characterized by X-ray diffraction (XRD), X-ray photoelectron spectra (XPS), Fourier transform IR (FTIR), scanning electron microscopy (SEM) and thermogravimetry-differential scanning calorimetry (TG-DSC). The SEM results indicate that the microspheres are self-assembled by numerous nanoflakes with mean thickness of 100 nm. Some factors influencing the morphologies of the Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O micro-/nanostructures have been systematically investigated, as well as quantity of glycine and the reaction time. The possible mechanism of the crystal growth and assembled procedure were also proposed. The as-prepared Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O can be transformed into Zn{sub 3}(VO{sub 4}){sub 2} with the similar morphologies by calcination in air at 600 Degree-Sign C. Furthermore, the photoluminescent propertiesmore » of both Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}{center_dot}2H{sub 2}O and Zn{sub 3}(VO{sub 4}){sub 2} were studied and exhibited different spectra.« less
