Figure 4

The comparison between nanosecond pumping of (a) QDs, (b) QRs and (c) NPLs. The arrows in each graph (red for QDs, orange for QRs and green for NPLs) represents the energy range, adopted for each case. The QRs and NPLs show clear indication of ASE at the peak wavelengths of 624 nm and 579 nm, respectively but only fluorescence is detected from QDs at the peak wavelength of 628 nm.
