“…No obvious impurity phase was detected. The XRD result shows that pure hexagonal-structured Zn 2 SiO 4 can be obtained at a low temperature of 140°C, which is lower than that of 220°C reported by Wan et al 55 and much lower than using the conventional solid-state reaction method. The XRD pattern in When CTAB as the surfactant molecules was added in the hydrothermal procedure, it was found that the size and the morphology of the Zn 2 SiO 4 :Mn 2+ phosphors could be controlled as shown in Fig.…”

“…Furthermore. the XRD result shows that pure hexagonal-structured Zn 2 SiO 4 can be obtained at the low temperature of 140℃, which is lower than the temperature of 220℃ reported by Wan et al [11] and much lower than that using the conventional solid-state reaction method. The average crystallite sizes estimated from the Scherrer equation indicated all the samples were in nanoscaled, and Zn 2 SiO 4 : Mn 2+ sample prepared at 220℃ represents the best crystal1inity.…”

, nano-sheets was obtained by solvent-thermal process, which reached 78.8% of the commercial red phosphor on emission intensity and exhibited better color purity than the latter. For ZnSiO 4 : Mn 2+ , different morphologies were obtained by hydrothermal method with varying ratio of CTAB to TEOS, among which the nano-spheres presented the strongest emission intensity and reached 86% of that of the commercial green phosphor. For BaMgAl 10 O 17 : Eu 2+ , nano-rods were acquired using sol-gel process, which exhibited 78.15% of the commercial blue phosphor on emission intensity and the low y value of color coordinates, which indicated that the nano-rods were efficient for restricting the deteriorate during application.

The controllable synthesis of materials with the desired crystal structure and dimensionality is of great significance in material science. In this work we report the successful synthesis of amorphous and crystalline zinc silicates with different dimensionalities and well-defined shapes, including hollow spheres, nanowires and membranes. The structure-related absorption properties have been studied. A detailed study of their ability to remove Pb(Ⅱ), Cd(Ⅱ), Cr(Ⅲ), and Fe(Ⅲ) ions has been performed. The amorphous zero-dimensional (0-D) hollow spheres show the best removal ability for all the metal ions investigated. In particular, their absorption capacity for Pb(Ⅱ) ions is 129 mg/g, which is double the value reported for magnesium silicate hollow spheres. However, the removal abilities of crystalline one-dimensional (1-D) nanowires and two-dimensional (2-D) membranes are found to be dependent on the charge of the target metal ion. In general, nanowires show better removal capacity for trivalent ions, especially Fe(Ⅲ), while 2-D membranes exhibit better removal capacity for divalent ions.
