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).
