Engineering surface states of carbon dots to achieve controllable luminescence for solid-luminescent composites and sensitive Be(2+) detection

Luminescent carbon dots (L-CDs) with high quantum yield value (44.7%) and controllable emission wavelengths were prepared via a facile hydrothermal method. Importantly, the surface states of the materials could be engineered so that their photoluminescence was either excitation-dependent or distinct...
