摘要：
The relaxation and recombination of carriers excited by ultrashort optical pulses are studied on specially prepared II-VI quantum dots in a silicate-type host. Photoluminescence with ps resolution allows to observe the emission from the confined, intrinsic energy levels of the dots under non-and size-selective excitation, respectively. A comparison with data of transient non-linear absorption reveals that the relaxation pathway of electron and holes may be substantially different and depends strongly on the dot size.
