Description
Carbon Quantum Dots (CQDs), 590–620 nm, DI Water
Carbon Quantum Dots (CQDs) with 590–620 nm orange emission are eco-friendly nanomaterials that exhibit vivid photoluminescence, excellent water dispersibility, and tunable optical properties. Their fluorescence originates from quantum-confined sp² carbon domains functionalized with carboxyl, hydroxyl, and amino groups, enabling pH-dependent emission, high stability, and facile chemical conjugation. Produced through green hydrothermal or microwave synthesis routes, these CQDs are non-toxic, photostable, and capable of achieving quantum yields above 30% with doping or surface passivation.
