摘要
We use a combination of hyperspectral superlocalization microscopy and excitation photoluminescence spectroscopy techniques to study the localization of one-dimensional excitons in pristine and functionalized single wall carbon nanotubes at low and room temperature. Using numerical simulations, we interpret the nearly resonant excitation spectra either in terms of excited trapped states leading a selective excitation of a trap or in terms of delocalized one dimensional excitonic states. We discuss the implications of this localization for the use of carbon nanotubes as quantum-light emitters. Raynaud et al. Nano Lett. 19, 7210 (2019)
