摘要：

Sr-5(PO4)(3)Cl:Eu2+ nanorod bundles were successfully prepared through a facile hydrothermal method, The X-ray diffraction (XRD) and FT-IR results demonstrate that the product is a pure hexagonal phase of Sr-5(PO4)(3)Cl. The scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-resolution TEM (HRTEM) images indicate that the as-prepared Sr-5(PO4)(3)Cl:Eu2+ nanorod bundles consist of parallel nanorods with diameters ranging from 20 to 30 nm and that the nanorods row along the [002] direction. The photoluminescence spectra show that the Eu3+ ions have been reduced to Eu2+ ions successfully and that the as-obtained Sr-5(PO4)(3)Cl:Eu2+ phosphor exhibited intense blue emission. Furthermore, this new simple synthetic route may be of much significance in the synthesis of other divalent europium ions activated nanoscale phosphors by aqueous method.
