| titleOfInvention | Method for synthesizing fluorescent carbon quantum dots by taking epoxy succinic acid and ethylenediamine as raw materials |
| abstract | The invention relates to a method for synthesizing fluorescent carbon quantum dots by taking epoxy succinic acid and ethylenediamine as raw materials. The invention comprises the following components in percentage by mass (0.5-3): 1, dissolving the epoxysuccinic acid and the ethylenediamine in ultrapure water in sequence, and uniformly stirring to obtain a reaction solution; and carrying out hydrothermal reaction on the reaction solution at 130-220 ℃ for 6-48 h, cooling to room temperature after the reaction is finished, and filtering by using a 0.22-micron filtering membrane to obtain the fluorescent carbon quantum dot. According to the invention, the epoxy succinic acid is used as a raw material for preparing the fluorescent carbon quantum dot for the first time, the component proportion and the optimal reaction condition of the epoxy succinic acid and the ethylenediamine are determined through a large number of experiments, the prepared carbon quantum dot has stable fluorescence performance and high fluorescence intensity, and the fluorescence intensity F of a 5ppm carbon quantum dot solution at the excitation wavelength of 314nm is 6681. The synthetic method is simple, the synthetic raw materials are cheap and easy to obtain, and the synthesized carbon quantum dots have stable fluorescence properties. |
