摘要
The composition and structure morphology of a dry colloid precipitate obtained by pure vanadium ablation in distilled water is analyzed by X-ray diffraction and electron microscopy. It is shown that the precipitate material is based on various vanadium oxides in the amorphous form. The precipitate represents a conglomerate of micrometer-sized particles composed of various layered structures of nanoscale thickness with a highly developed surface. These features of vanadium oxide nanostructures imply their promising application as efficient substrata in the analytical method based on surface-enhanced Raman scattering.
