Figure 1. (a) A schematic illustrating the graded alloyed core-shell structure of CdZnSe/ZnSe/ZnxCd1-xS CQDs. (b) Spectra of the CQDs, including PL, linear absorption, and second-order differential absorption. (c) Evolution of PL spectra of the CQDs with increasing pump intensity under sub-nanosecond pulsed laser excitation. (d) The dependence of spontaneous emission and ASE intensity of the CQDs on pump intensity.
