Facile synthesis of carbon dots in an immiscible system with excitation-independent emission and thermally activated delayed fluorescence†
Abstract
Herein, we present a one-pot microwave-assisted preparative method for water-soluble carbon dots (CDs) in an immiscible system. CDs demonstrated uniform morphology, high quantum yield and excitation-independent fluorescence emission. Moreover, we first reported the observation of thermally activated delayed fluorescence from CDs.
