摘要：

Lanthanum carbide nanotubes have been synthesized by d.c. arc evaporation (similar to20-30 V, similar to200 Amp) of lanthanum metal (90 wt.%)-loaded graphite rod in a helium atmosphere (665 mbar). To explore the possibility of formation of lanthanum carbide nanotubes, the experiments were carried out with lanthanum metal in different concentrations (i.e., 30, 50, 70, and 90 wt.%) in the graphite rod. The as-synthesized samples were characterized by transmission electron microscopy and X-ray diffractometry. Lanthanum carbide nanotubes (LCNTs) with a diameter of similar to65 to 95 nm and a length of similar to0.2 to 1.5 mum were obtained in this study.
