摘要: 用酸回流法制备了荧光碳点，研究了碳点的光致发光行为对浓度的依赖关系，实验表明，碳点的光致发光性能可以通过碳点的浓度来调控，这将为碳点的应用提供新的途径。本文还结合碳点表面结构和形貌的表征，分析了浓度对碳点荧光行为的调控机制，为进一步澄清碳点的发光机制提供了一定的参考。
Abstract: Fluorescent carbon dots were prepared by acid reflux method. The dependence of the photolumi-nescence (PL) behavior of the carbon dots with its concentration was studied. The results show that the PL properties of carbon dots can be tuned by its concentration. This will provide a new way for the application of carbon dots. Moreover, combing with the surface structure and morphology characterization of carbon dots, the modulation mechanism of concentration was analyzed, which can provide some reference for further clarifying the PL mechanism of carbon dots.
