Abstract: In the present study, highly fluorescence carbon dots (CDs) were synthesized by one step hydrothermal method using citric acid (CA) as carbon source and 1,2-ethylenediamine (EDA) as passivation agent. The samples of CDs under different reaction temperature were prepared and evaluated by FT-IR, UV-vis and fluorescence detection to estimate and summarize the forming rules and fluorescence mechanism of CDs. Results indicated the optimal reaction temperature was 200 oC, the quantum yield were measured to be 79.7%. The fluorescence of CDs was determined by carbon core and surface state and its forming process mainly included the steps of cracking, polymerization, carbonization and growth of nuclei. The as-prepared CDs had excellent water solubility and biocompatibility, which held a great potential in the fields of cell targeting and drug delivery.
