摘要

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。

Carbon dots as reductants to fabricate three-dimensional Au mesoflowers as SERS substrates

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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
