single-walled carbon nanotubes produced by laser ablation under different inert atmospheres

摘要

In this work, single-walled carbon nanotubes(SWNTs) have been produced under atmospheres of argon,nitrogen, mixture of argonitrogen, and helium using acontinuous wave model CO_2 laser. High amount of SWNTmaterial was achieved when argon and nitrogen and its mixturewere employed as buffer gases, both under static and dynmicconditions, as it was observed by electron microscopy. In contrastto the arc-discharge method, very low yields were obtainedworking under helium atmospheres.
