| Popis: | Hydrogenated and fluorinated single‐walled carbon nanotubes (SWNT‐H and SWNT‐F) were investigated by micro‐Raman spectroscopy. The as‐prepared SWNT‐H exhibits giant structureless hot luminescence that screens the Raman peaks. The luminescence background, attributed to random binding of the hydrogen atoms, gradually decreases upon annealing of the sample. In contrast, the as‐prepared SWNT‐F shows no luminescence but the Raman peaks are rather broad. The annealing of SWNT‐F results in structural ordering due to fluorine removal. |
