“…4(b) from the time-dependent PL spectral image. This can be explained by the formation of charged excitons with fluctuating local fields to disturb the exciton energy by means of the Stark effect [16,17]. We attribute the red-shifted PL peak to be from X -s, whose PL photons are mixed with those from Xs in the blinking "on" intensity levels of the room-temperature PL time trace measured at <N> = ~1.7…”

“…3(b) from the time-dependent PL spectral image of a representative NC. PL linewdiths as narrow as hundreds of μeV were occasionally observed in single CdSe NCs at the cryogenic temperature [17,19], however, their stability over a long measurement time like the one shown in Fig. 3(b) has never been reported in literature.…”

“…raster scanning) imaging. Indeed, they exhibit a complex pattern of intermittency [20][21][22][23] , which results in a patchy image of the excitation PSF, as built up from the fluorescence emitted by a single nanocrystal. Figure 3 gives an example of multicolor imaging of a mixture of 4 batches exhibiting striking example of "blinking" nanocrystals.…”

“…Time series of single line spectra with short integration time (80-300 ms) show slight stochastic variations of the peak energies and intensities due to fluctuating electric fields. The source of these fields is charging and discharging of nearby defects or interface states [24,25]. This effect can be used to correlate transitions that originate from the Same QD, since they experience the Same electric fields, and hence, the lines exhibit the Same energetic jitter and intensity behavior [26].…”
