Individual CuZn-VS defects in colloidal ZnS:Cu nanocrystals emit antibunched, blinking red light at room temperature, with polarization consistent with a sigma-dipole transition.
9 STEM images are taken using a JEOL NEOARM elec- tron microscope with Cold-FEG emission source oper- ated at 200 kV

Room-temperature quantum emission from $\mathrm{Cu_{Zn}}$-$\mathrm{V_{S}}$ defects in ZnS:Cu colloidal nanocrystals
Individual CuZn-VS defects in colloidal ZnS:Cu nanocrystals emit antibunched, blinking red light at room temperature, with polarization consistent with a sigma-dipole transition.
