| titleOfInvention | A kind of nitrogen sulphur is co-doped with the preparation method of graphene quantum dot |
| abstract | The present invention proposes a kind of straightforward procedure of nitrogen and sulphur codope graphene quantum dot.Due to the nitrogen-atoms of doping and the synergistic effect of sulphur atom, the nitrogen sulphur of gained, which is co-doped with graphene quantum dot (N, S-GQDs), has up to 73% fluorescence quantum yield (being equivalent to strong blue-fluorescence), and does not depend on feature with excitation.The preparation method uses common source material, at low cost, and yield is high, and is single step technique, therefore, is of great significance to large-scale production, is conducive to the popularization and application of graphene quantum dot.It is disclosed that a kind of nitrogen sulphur is co-doped with the preparation method of graphene quantum dot, this method includes heating the mixture of carbon source and nitrogenous element sulphur compound in autoclave, this contains nitrogen sulfur compound and may include at least one of L-cysteine, thiocarbamide, mercaptoethylmaine, glutathione and methionine, which may include at least one of citric acid and malic acid. |
