Stability Criteria of Fullerene-like Nanoparticles: Comparing V₂O₅ to Layered Metal Dichalcogenides and Dihalides.

ABSTRACT: Numerous examples of closed-cage nanostructures, such as nested fullerene-like nanoparticles and nanotubes, formed by the folding of materials with layered structure are known. These compounds include WS₂, NiCl₂, CdCl₂, Cs₂O, and recently V₂O₅. Layered materials, whose chemical bonds are highly ionic in character, possess relatively stiff layers, which cannot be evenly folded. Thus, stress-relief generally results in faceted nanostructures seamed by edge-defects. V₂O₅, is a metal oxide compound with a layered structure. The study of the seams in nearly perfect inorganic "fullerene-like" hollow V₂O₅ nanoparticles (NIF-V₂O₅) synthesized by pulsed laser ablation (PLA), is discussed in the present work. The relation between the formation mechanism and the seams between facets is exa
