%X Recent success in
Mn2+ ion doping in cesium lead halide (CsPbX3) nanocrystals opened the door to exploring new optical, magnetic
and charge carrier transport properties mediated via exciton–dopant
exchange coupling in this new family of semiconductor nanocrystals.
Here, we studied the dynamics of energy transfer from exciton to Mn2+ ions in Mn-doped CsPbCl3 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 CsPbCl3 nanocrystals and CdS/ZnS core/shell quantum
dots suggests that exciton–Mn exchange coupling in CsPbX3 is not far behind that of CdS/ZnS despite the lack of quantum
confinement. With further progress in the synthesis of Mn-doped CsPbX3 nanocrystals, such as imposing quantum confinement and expanding
the range of host chemical composition, one could fully benefit from
many properties of CsPbX3 superior to those of other semiconductor
nanocrystals for hosting magnetic dopants.
