Iron Bromide in the Channels of Single-Wall Carbon Nanotubes
摘要
Abstract
The channels of single-walled carbon nanotubes (SWCNTs) are filled with iron bromide FeBr2. Images of the filled SWCNTs are obtained using transmission electron microscopy. The Raman spectra of the filled SWCNTs are studied. A shift of peaks towards higher frequencies is observed. The X-ray photoelectron spectra of the filled SWCNTs are studied; it is found that charge density transfer occurs between the nanotubes and the embedded FeBr2.
