Recent advances in nanocrystal doping chemistries have substantially broadened the variety of photophysical properties that can be observed in colloidal Mn{sup 2+}-doped semiconductor nanocrystals. A brief overview is provided, focusing on Mn{sup 2+}-doped II-VI semiconductor nanocrystals prepared by direct chemical synthesis and capped with coordinating surface ligands. These Mn{sup 2+}-doped semiconductor nanocrystals are organized into three major groups according to the location of various Mn{sup 2+}-related excited states relative to the energy gap of the host semiconductor nanocrystals. The positioning of these excited states gives rise to three distinct relaxation scenarios following photoexcitation. A brief outlook on future research directions is provided. - Graphical abstract: Mn{sup 2+}-doped semiconductor nanocrystals are organized into three major groups according to the location of various Mn{sup 2+}-related excited states relative to the energy gap of the host semiconductor nanocrystals.
