Here comes your Mn : Semiconductor nanocrystals doped with manganese exhibit dual emissions that are dependent on the excitation intensity. Under single‐wavelength excitation, the emission color of these doped nanocrystals can be tuned from orange to blue at different excitation fluences. This color‐tunable property is reversible and originates from the excitation of multiple Mn dopants inside a nanocrystal.
