Реферат: Diameter of single-walled carbon nanotubes (SWCNTs) determines the possibility to encapsulate molecules and governs the type of structures that can be formed inside the tubes [1,2]. Differences between the encapsulated structures, such as coronene molecules stacks and graphene nanoribbons (GNR), were detected and studied via Raman and photoluminescence (PL) spectroscopies. We show the importance of the PL excitation mapping in a wide spectral range in order to clearly detect the spectral features specific to coronene stacks or GNR inside the nanotubes. We pay particular attention to the by-products that can be formed on the outside surface of nanotubes. Raman spectroscopy was used to study aggregates that were extracted from filled SWCNTs by sonication and density gradient centrifugation processes.
