C-纳米点的尺寸可以通过在其制备期间改变所施加的电势来电化学调节。所施加的电势越高，所得的C纳米点越小。此外，C-纳米点的表面氧化程度也可以电化学调节。碳纳米点的发射红移与其尺寸无关，这为碳纳米点的发光机制提供了一个新的视角。
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.
