Quantum dots acting as single photon emitters in the blue-green range arefabricated and characterized at cryogenic temperature. They consist in CdSedots inserted in (Zn,Mg)Se nanowires with a thick shell. Photoluminescencespectra, decay curves and autocorrelation functions were measured undernonresonant continuous-wave and pulsed excitation. An analytical approach isapplied simultaneously to the decay curves and correlation functions. It allowsa quantitative description of how these two quantities are affected by theexciton rise due to biexciton feeding, the bright exciton decay, the effect ofthe dark exciton, and the re-excitation between two laser pulses. Linewidths atour limit of resolution (200 $\mu$eV) are recorded. The reported correlationcounts vary from a full control by re-excitation from traps, to a smallcontribution of re-excitation by mobile carriers or other QDs, as low as 5%.
