Tóm tắt

The absence of the enhancement of fluorescence in carbon dots (CDs) through doping with transition metal atoms (TMAs) hinders the advancement of multi-modal bio-imaging CDs with high photoluminescence quantum yield (PLQY). Herein, Mn-atomically-doped R-CDs (R-Mn-CDs) with a high PLQY of 41.3% in water is presented, enabling efficient in vivo dual-mode fluorescence/magnetic resonance (MR) imaging. The comprehensive characterizations reveal that the incorporation of Mn atoms leads to a Mn-N
