Figure 4

(a) Emission intensity of the nanocrystal populations whose photoluminescence contributions are indicated in the inset, normalized to their respective emission intensity below the CM threshold. 50% CM efficiency is being assumed for all NC sizes. (b) Emission intensity ratios calculated from the curves in (a) The temporary decrease (negative peak) shifts in position and magnitude when the difference between the compared fractions is larger. (c) Emission intensity of nanocrystal populations B and D (see inset), where the emission of B increases less than (B−), equally to (B) and more than (B+) that of D. (d) Emission intensity ratios calculated from the curves in (c). The ratio exhibits distinctly different behavior, depending on the difference in CM efficiency of the individual populations.
