Luminescence in colloidal Mn{sup 2+}-doped semiconductor nanocrystals
- Department of Chemistry, University of Washington, Seattle, WA 98195 (United States)
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.
