Show affiliationsSingle-crystalline nanobelts of a nonstoichiometric compound Cu1.55V2O6.55, with a thickness of 40–60 nm, width of 50–300 nm and length of several micrometers, have been synthesized on a large scale by a hydrothermal method. The structures and morphologies of the nanobelts were characterized by x-ray powder diffraction, x-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy and high-resolution transmission electron microscopy. A probable growth mechanism has also been discussed. The nanobelts exhibit a turn-on field of 11.0 V µm−1, which is defined as the macroscopic field required to produce a current density of 10 µA cm−2. It is anticipated that the nanobelts can serve as a candidate material for future field emitters.
