摘要：

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. Copyright © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
