摘要：

The size of C-nanodots can be electrochemically tuned by changing the applied potential during their preparation. The higher the applied potential, the smaller the resulting C-nanodots. Moreover, the surface oxidation degree of the C-nanodots can also be electrochemically tuned. The redshift of emission independent of the size provides an insight into the luminescence mechanism of C-nanodots.
