Implication

Mechanistic study reveals surface oxidation and particle size tune photoluminescence in carbon nanodots, highlighting pathways to control nanoscale optical properties.

Key Points

To determine how surface chemical modifications and particle size regulate surface-state energy gaps and photoluminescence emission in carbon nanodots.
Analyzed the effects of increasing surface oxidation levels on surface-state electronic transitions.
Evaluated how expanding the core π-electron system in larger carbon nanodots couples with surface electronic states.
Increasing the degree of surface oxidation directly narrows the surface-state energy gap.
Enlarging particle size expands the core π-electron system, coupling with surface states to further narrow the energy gap and tune emission.
