The Change of the State of an Endohedral Fullerene by Encapsulation into SWCNT: A Raman Spectroelectrochemical Study of Dy3N@C80 Peapods
Raman and in situ Raman spectroelectrochemical studies of Dy3N@C80@SWCNT peapods have been carried out for the first time. The formation of peapods by the encapsulation of gaseous Dy3N@C80 has been confirmed by HR‐TEM microscopy and by the successful transformation of Dy3N@C80@SWCNT into double‐wall...

| description | Raman and in situ Raman spectroelectrochemical studies of Dy3N@C80@SWCNT peapods have been carried out for the first time. The formation of peapods by the encapsulation of gaseous Dy3N@C80 has been confirmed by HR‐TEM microscopy and by the successful transformation of Dy3N@C80@SWCNT into double‐walled carbon nanotubes. The Raman spectra of the endohedral fullerene cluster changed dramatically in the interior of the single‐walled carbon nanotube (SWCNT). The electrochemical charging of the peapod indicates a slight reversible attenuation of the Raman intensities of fullerene features during anodic doping. The results support the assignment of Raman bands to the Dy3N@C80 moiety inside a SWCNT.
Peas in a pod! Dy3N@C80@SWCNT endohedral fullerene peapods have been synthesized and characterized by Raman spectroscopy (see figure) and in‐situ Raman spectroelectrochemistry. |
