Here, we studied the dynamics of energy transfer from exciton to Mn<sup>2+</sup> ions in Mn-doped CsPbCl<sub>3</sub> nanocrystals to gain an insight into the relative strength of exciton–Mn exchange coupling compared to more extensively studied Mn-doped II–VI quantum dots. The comparison of exciton–Mn energy transfer times in CsPbCl<sub>3</sub> nanocrystals and CdS/ZnS core/shell quantum dots suggests that exciton–Mn exchange coupling in CsPbX<sub>3</sub> is not far behind that of CdS/ZnS despite the lack of quantum confinement. With further progress in the synthesis of Mn-doped CsPbX<sub>3</sub> nanocrystals, such as imposing quantum confinement and expanding the range of host chemical composition, one could fully benefit from many properties of CsPbX<sub>3</sub> superior to those of other semiconductor nanocrystals for hosting magnetic dopants.
