Abstract

Reductive carbon dots (CDs) were obtained by a hydrothermal method using citric acid and diethylenetriamine as carbon sources. Three-dimensional Au mesoflowers (3D Au MFs) could be fabricated by directly mixing HAuCl4 and CD solution without using any extra reductant and morphology-directing reagent. The as-obtained 3D Au MFs exhibited high surface-enhanced Raman spectroscopy (SERS) activity in detection of methylene blue.

以碳点为还原剂制造三维金介质流作为 SERS 基底

以柠檬酸和二乙烯三胺为碳源，通过水热法获得了还原性碳点（CD）。将 HAuCl4 与 CD 溶液直接混合，无需使用任何额外的还原剂和形态定向试剂，即可制备出三维金介花（3D Au MFs）。制得的三维金介花在检测亚甲基蓝时具有很高的表面增强拉曼光谱（SERS）活性。
