摘要：

Unlimited possibilities: Light-driven modulation of the fluorescence from Mn-doped ZnSe quantum nanocrystals has been established through excited-state absorption and its direct competition with spontaneous emission. Such optical control over electronic transitions enables far-field fluorescence microscopy analysis with diffraction-unlimited resolution (45 nm, red) based on quantum dots (confocal imaging has a resolution of 200 nm, blue).
