Abstract

A one-step hydrothermal strategy has been developed to fabricate 3D flower-like hierarchical microstructures assembled by hexagonal NaReF4 nanosheets. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and high resolution transmission electron microscope (HRTEM) techniques. It was found that oxalic acids and the pH value have great effects on the shape of the final product. A possible formation mechanism has been proposed. Photoluminescence (PL) displays that the emission intensity of the 3D flower-like NaReF4 hierarchical microstructures was higher than that of NaReF4 oblate structures. These 3D flower-like NaReF4 hierarchical microstructures may have potential applications in sensors, optics, and visible emitting devices.
