Description
| - Ramanská spektroskopie a in-situ Ramanská spektroelektrochemie byla použita pro studium chemických dopantů uvnitř dvojstěnných uhlíkových nanotub (DWCNT) po dopování draslíkovou parou. Silné dopování bylo potvrzeno zmizením signálu radiálního dýchacího modu (RBM) vnějších tub. RBM vnitřních tub bylo možné detekovat i přes silné dopování. U dopovaných vzorků se ve spektrech objevily RBM vnitřních tub, které nebyly v rezonanci v případě nedopovaných vzorků. Odstranění draslíku z dopovaných DWCNT vedlo k téměř kompletnímu obnovení původních DWCNT spekter. U vzorků, které byly hydrolyzovány vodou byla možná přítomnost draslíku uvnitř DWCNT dále studována pomocí electrochemického dopování. (cs)
- The Raman spectroscopy and in situ Raman spectroelectrochemistry have been employed to evaluate the state of chemical dopants in the inner space of potassium vapor treated double walled carbon nanotubes (DWCNT) for samples heavily doped. The doping level was confirmed by the disappearance of the radial breathing mode (RBM) signal of outer tubes. The RBMs of inner tubes are still detected even after heavy doping. Furthermore the Raman spectra of doped samples show the RBM of inner tubes, which were not in resonance for undoped sample. The removal of potassium from doped DWCNT led to an almost complete recovery of the DWCNT spectra. The possible presence of potassium inside DWCNT has been investigated by electrochemical charging after a treatment of the sample with water.
