Exciton emission lifetime (slow component) for CsPbCl3:Mn2+ (9, 20, and 32 atom %) NCs as a function of temperature. (a) Evolution of lifetime of CsPbCl3:Mn2+ (9, 20, and 32 atom %) NCs with temperature. (b) Three-level fitting of the long decay component of CsPbCl3:Mn2+ (20 atom %) NCs exciton decay versus temperature.
