Abstract

The femtosecond transient absorption and time-resolved photoluminescence studies of ultrafast energy relaxation and recombination in II-VI semiconductor nanocrystals (NC) with a variety of sizes, spanning different confinement regimes are reported. The issue on the existence of the `phonon bottleneck' is addressed in carrier relaxation dynamics predicted for quantum confined systems. Surface trapping in NC with different surface treatment and many-particle Auger-type interactions are also reported in case of multiple-pair excitations.
