Silane-functionalized carbon dots for full-spectrum white light-emitting diodes

A solvent-polarity-directed strategy has been developed to synthesize multicolor silane-functionalized carbon dots from citric acid and an organosilane through a solvothermal reaction. These synthesized silane-functionalized carbon dots can then be integrated with a violet-emitting chip to fabricate a full-spectrum white light-emitting diode, showing a color rendering index of 92.
