Figure 3
Examples of narrow spectral lines. (a, b) Examples of time series of consecutive single-NC spectra (offset for clarity) acquired at one specific spot. Temperatures are noted in each panel. Panel a illustrates exceptionally narrow type-Ib spectra measured at room temperature (kBT = 25.85 meV). This time series shows blinking, thus confirming that the emission originated in one specific NC. Panel b presents spectra with the narrowest observed lines (kBT at 20 K is 1.7 meV; the linewidth values are deconvolved with the spectral resolution of the system). The gray curves serve as guides-to-the-eye. (c, d) Averages of the spectra from the panels above them designated with the ellipses.
