AbstractWe collect and spectrally resolve photoluminescence from single CdSe nanocrystallite quantum dots. By eliminating spectral inhomogeneities, we reveal resolution limited linewidths < 120μev at 10K. These lines are more than fifty times narrower than what has previously been reported using ensemble measurements. Light driven spectral diffusion is seen as a form of power broadening and may be the cause of surprisingly broad linewidths at room temperature. In addition, we see no evidence of excited state emission or coupling to acoustic phonons.

In this study, the photostability of a CdTeSe/ZnS colloidal single photon emitter with a wavelength of 800nm at room temperature was investigated. The second-order correlation function was much smaller than 0.1, which proved that the CdTeSe/ZnS single quantum dot at 800nm is a highly pure single-photon emitter. The effects of the irradiation time on the optical properties from single quantum dots were analyzed. As the illumination time increased, the emission of biexciton and multiexciton in the colloidal quantum dots increased, and the occurrence of Auger recombination increased.
