We use transient photoluminescence to spectrally resolve the emission from 1, 2, and 3 electron–hole pairs states in CdSe colloidal nanocrystals with radii ranging between 2.3 and 5.2nm. Temporally and spectrally resolved multiexciton emission from single NCs is also observed. The observation of multiexciton emission enables new experiments and potential applications at both the single NC level and...
Single organic molecules spread on a thin semiconductor film probe local electrical currents. For low DC voltages, we measure strong quadratic line shifts with thresholds at higher voltages. Under AC voltages, the shifts of most molecules display resonances between 10kHz and 1MHz, with frequencies and shapes differing from molecule to molecule within the laser spot. For high enough DC voltages, auto-oscillations...
