Abstract

We present that in the case of picosecond durations, the limitation efficiency of laser radiation and absorption kinetics in CdSe/ZnS colloidal solutions is determined by Auger relaxation through the 1S(e) states. In the observed kinetics of a probe-pulse transmission, the “delayed limitation” effect has been detected. Numerical modeling has made it possible to identify the competition between the next two relaxation processes of highly excited states: relaxation through size quantization levels and phononless relaxation through traps states.
