Hydrothermal Route

We used a simple hydrothermal route to obtain EDE N-CDs or EIE N-CDs. The fluorescence of the as-prepared CDs could be quenched by cellular Hg2+ owing to the electrons transfer from CDs to Hg2+.

Doped Carbon Dots

Europium (Eu) doped carbon dots (CDs) were synthesized via a rapid and simple microwave mediated method using polyethylene glycol (PEG) as a precursor, and characterized in detail. The results were that these as-prepared CDs showed a uniform and small particle size, and exhibit good photostability and high photoluminescence quantum yields. Additionally, it also found that the doped Eu would change the fluorescence properties, which indicates potential applications in the field of biolabeling.
