摘要
近几年,碳点作为一种新型荧光纳米材料,由于其优良的物理化学和光学性能成为研究者们研究的热点材料之一,并被应用于传感器、催化、降解、生物成像等方面。碳点的特性不仅受发射波位置的影响,也与其粒径的大小存在密切的联系。目前大多数研究焦点都在碳点制备方法和应用研究上,而碳点的纯化问题却很少有全面的报道。本文将针对近些年碳点的纯化方法进行综述,为碳点的纯化过程提供参考,对于碳点的进一步研究和应用具有非常重要的意义。
In recent years, as a new fluorescent nanomaterial, carbon dots have become one of the popular studied by researchers because of their excellent physical and chemical properties, and are widely used in sensors, catalysis, degradation, and bioimaging, etc. The characteristics of the carbon dots are not only affected by the position of the emitted wave, but also closely related to the particle size. To date, most researches focus on the preparation methods and applied re-search of carbon dots, while the purification of carbon dots is rarely reported comprehensively. This paper will review the purification methods of carbon dots in recent years and provide ref-erence for the purification process of carbon dots. It is of great significance for the further re-search and application of carbon dots.
