a)Near-field PL image of single-walled carbon nanotubes on mica formed by detecting the total PL between 860 and 1050 nm upon laser excitation at 632.8 nm and 5 mW.
b)Near-field PL spectra recorded along the structure reveal that it is a bundle composed of two nanotubes with different emission energies.
