Semiconducting carbon nanotubes exhibit excitonic transitions in the near-infrared. The past decades have established an extensive understanding of carbon nanotubes photophysics mainly based on room-temperature studies. More recently, cryogenic spectroscopy has identified non-classical emission from individual nanotubes which can be accompanied by spectrally narrow emission. We will present our latest results obtained with photoluminescence spectroscopy of single carbon nanotubes both at room and cryogenic temperatures and discuss the dependence of low-temperature spectra on transverse electric field.
