Abstract

original image

Narrow diameter and highly crystalline triple-walled carbon nanotubes (TWNTs) are prepared from high-temperature treatment of double-walled carbon nanotubes encapsulating fullerenes at high temperatures in the range of 1500–2400 °C. The TWNTs have high structural stability and unique physical properties that are observed in the Raman and fluorescent signals.
