NaV2O5 crystals of a right-angle-shaped nanostructure assembly

Abstract

L-shaped NaV₂O₅ crystals with two straight arms were controllably synthesized in a hydrothermal system with the assistance of 1,3,5-benzentricarboxylate acid (H₃BTC). The arms were assembled by nanowires grown along the b-direction. By means of transmission electron microscopy, the (310) twin boundary was found to connect the nearly perpendicular arms to form the L-shaped structure. Meanwhile, the L-shaped crystallites, as the basic unit, can be further self-assembled into ┤ and + shapes.
