초록

We report a monochromatic dual-emission carbon nanodot (CD) as an unusual ratiometric fluorescence probe. The CD exhibits fluorescence spectral change from monochromatic blue to green emission, which is induced by Fe(III) ions as well as hydroxyl radicals. The monochromatic fluorescence spectral change of CD is utilized for a ratiometric fluorescence assay distinguishing Fe(III) and Fe(II) in aqueous media.
