Large-Scale Production of NbS2 Nanowires and Their Performance in Electronic
Emission. — Large quantities (hundreds of milligrams) of the title nanowires are
52- 206 Field
prepared by direct heating Nb and S powders in sealed quartz tubes in the presence of
I2 (800 °C, 3 d). The samples are characterized by XRD, SEM, TEM, EDX, and magnetic measurements. As revealed by repeating field emission tests the NbS2 nanowires
are highly reliable field emitters and exhibit a very low turn-on voltage, which is among
of the best inorganic one-dimensional nanomaterials and is comparable with those of
carbon nanotubes. — (JIN, Y. Z.; HSU, W. K.; CHUEH, Y. L.; CHOU, L. J.; ZHU*, Y.
