Temperature‐dependent magneto‐photoluminescence spectroscopy of carbon nanotubes: evidence for dark excitons

“…Time-resolved optical spectroscopy [22][23][24][25][26][27][28][29] revealed details of decay processes of photo-excited carriers, excitons, and phonons. Various microscopies [30][31][32][33][34] have collected signals from individual nanotubes. Magneto-optical studies [35][36][37][38][39] have begun to reveal details of the excitonic structure.…”

Direct observation of dark exciton states in single carbon nanotubes

“…Since the exciton state in carbon nanotubes has a well-defined quasi-1D character, the PL intensity of a single carbon nanotube is expected to be proportional to cos 2 y, indicated by the line of the inset in Fig. 3(a) [18][19][20]. This strong PL anisotropy is useful for determining the direction of the carbon nanotube axis on the patterned substrate.…”

Nanoscale optical imaging of single-walled carbon nanotubes

“…Both, photoluminescence (PL) and Raman spectroscopy combined with conventional microscopy have been used extensively to study the structural properties of SWNTs (see e.g. [10][11][12][13]). Recently, we demonstrated near-field Raman microscopy of individual SWNTs with high spatial resolution [4,14].…”
