Both a near‐infrared (NIR) absorption band and enhanced NIR fluorescence are realized by Songnan Qu, Andrey L. Rogach, and co‐workers, in article number 1705913 , through surface engineering of carbon dots, exploiting electron‐acceptor groups, namely molecules or polymers rich in sulfoxide/carbonyl groups. Twophoton‐induced NIR emission and three‐photon‐induced red emission are simultaneously observed for carbon dots in dimethyl sulfoxide under excitation of a 1400 nm femtosecond pulse laser in the NIR‐II window.
