Extended Data Fig. 4: Temperature-dependent PL measurement.

2D colour map of temperature-dependent PL spectra of a, pristine ZnSe/ZnS QDs and b, Cl:ZnSe/ZnSe/ZnS QDs, respectively. The temperature stable PL emissions of Cl doped QDs may result from a combined effect of reduced thermal expansion and enhanced energy transfer from the FE to the STE states.
