Figure 5

(a) Time-resolved ellipticity signals of as-grown colloidal CdSe QDs and QDs with 1-octanethiol (OT) prepared in an air atmosphere. The inset is the corresponding FFT spectra. The FFT spectroscopy of as-grown CdSe QDs is multiplied by 8 for clarity. The molar ratio of OT to CdSe QDs is 11,000. The laser repetition rate is 50 kHz. (b) Spin signals of as-grown colloidal CdS QDs and QDs with OT prepared in an air atmosphere. The inset is the corresponding FFT spectra. The FFT spectroscopy of as-grown CdS QDs is multiplied by 7 for clarity. The molar ratio of OT to CdS QDs is 5000. The laser repetition rates for as-grown CdS QDs and QDs with OT are 50 and 10 kHz, respectively.
