a Fluorescence image of a 4 × 4 array of single-photon single colour centres induced by the same pulse energy. b Fluorescence saturation curve with a saturation count of 9 Mcounts s-1 with a saturation power of 764 μW. c Emission polarisation curves from the emitter. d The time series of PL spectra from the emitter. e Intensity time trace with a binning time of 50 ms acquired by APDs through the time-gated time-resolved method. The intensity histogram is plotted on the right
