Synthesis and characterization of novel flower-like CeF_3 nanostructures via a rapid microwave method

摘要

Novel flower-like CeF_3 nanostructures with a mean diameter of 190 nm were successfully synthesized via a rapid and facile microwave irradiation route using ethylenediaminetetraacetic acid disodium as the complexing reagent. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and photoluminescence (PL). XRD patterns showed that the CeF_3 nanoflowers were hexagonal phase and had good crystallinity and purity. TEM and SEM images showed that the as-prepared CeF_3 samples displayed 3D flower-like nanostructures and had uniform sizes and morphologies. The experimental results revealed that the as-prepared CeF_3 nanoflowers might be assembled by nanodisks. The formation process of the CeF_3 nanoflowers was preliminarily investigated.
