以天然紫菜多糖（PPS）为单一碳源，乙二胺（艾德）为表面钝化剂，采用一锅法水热碳化反应合成了多功能荧光碳点（CD）。所得CD具有高量子产率（56.3%）、激发依赖荧光、小尺寸（
In this study, multifunctional fluorescent carbon dots (CDs) were synthesized using a one-pot hydrothermal carbonization reaction, with the naturally-occurring porphyra polysaccharide (PPS) serving as a single carbon source for the first time and ethylenediamine (Ed) acting as the surface passivation agent. The resulting CDs enjoyed a high quantum yield (56.3%), excitation-dependent fluorescence, small size (
