The first rare-earth fluoride one-dimensional nanostructures: template synthesis of LnF 3 (Ln=Eu, La) nanotubes

Abstract

Uniformly ordered crystal EuF₃ and LaF₃ nanotubes were prepared using alumina film as a nanochannel reactor, and characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray powder diffraction (XRD). These nanotubes have outer diameters in the range of 200–350nm, inner diameters of 100–250nm and length up to 30μm. The fabrication method is simple, efficient and easy to control. It can be used to prepare a wide range of inorganic nanomaterials.
