Fig. 3: Statistical dispersion of individual SPE properties.

a g⁽²⁾(0) of 10 SPEs, showing single-photon emission. b Fluorescence lifetime τ of the same 10 individual SPEs, with a mean value of 1.87 ns. c Polarization axis of the emission of 6 individual SPEs on the same flake, showing that most SPEs emit with a similar polarization direction.
