“…If we use the exciton recombination time of CdSe QDs (obtained in an earlier study) to be 450 ps [12], the spin relaxation time for this QD system is in the range of a few nanoseconds, in rather good agreement with recent studies done by others on similar QD systems [7,13]. It is interesting that the g-factor (0:42 AE 0:08) obtained from the fitting is almost identical to those reported for the conduction electron g-factor ðg ¼ 0:42Þ in CdSe [14]. It is well known that spin polarization of the holes in the valence band undergoes rapid dephasing [15].…”

The electron spin coherence in n-doped and undoped, self-assembled CdSe/Zn(S,Se) quantum dots has been studied by time-resolved pump-probe Kerr rotation. Long-lived spin coherence persisting up to 13 ns after spin orientation has been found in the n-doped quantum dots, outlasting significantly the lifetimes of charge neutral and negatively charged excitons of 350 − 530 ps. The electron spin dephasing time as long as 5.6 ns has been measured in a magnetic field of 0.25 T. Hyperfine interaction of resident electrons with a nuclear spin fluctuations is suggested as the main limiting factor for the dephasing time. The efficiency of this mechanism in II-VI and III-V quantum dots is analyzed.

“…The values of the g-factors are similar to those of bulk ZnSe (1.16) and much larger than those of CdSe (0.42) [5]. SFRS spectra were measured for values of q ranging from 0 to 90 .…”

Resonant spin-flip Raman scattering in tilted magnetic fields up to 14 T has been used to investigate excitons localised by the random disorder created by sub-monolayer insertions of CdSe in a ZnSe matrix. The field dependences of the Raman shifts, of the linewidths of the signals and of their intensities have been measured and fitted by a simple theoretical model and the g-factors and exchange parameters have been determined. It is concluded that spin-flip of the total exciton spin is one of the important mechanisms of spin relaxation.
