 Carbon dots, CDs, which are composed of sp3 hybridized carbon cores with partially sp2 hybridized carbon atoms, have been shown to emit full-spectrum colors when exposed to light. This makes them ideal for use in white light emitting diodes, LEDs. A new method has been developed to produce these CDs in a single reaction system, allowing for easy control of the reaction conditions. Furthermore, slight modifications of the reaction conditions allow for the production of CDs with different colors, making it possible to create LEDs with full-color emission.
