Fluorescent Carbon Dots

The pH-dependent properties of carbon dots (CDs), decorated with surface carboxylic acid functional groups, are described. Absorption, fluorescence emission measurements were used to study the reversible pH-dependent spectral response. The pH-dependent emissions of CDs demonstrate a strong dependence on the excitation wavelengths and make the as-prepared CDs a good ratiometric pH-sensor candidate. This green material CDs-based probe shows promising potential for probing pH in real sample and in vivo intracellular imaging.
