摘　　要：荧光碳点是继富勒烯、碳纳米管及石墨烯之后最热门的碳纳米材料之一。这种纳米材料克服了传统量子点的某些缺点,不仅具有优良的光学性能与小尺寸特性,而且具有良好的生物相容性,易于实现表面功能化,在生化传感、成像分析、环境检测、光催化技术及药物载体等领域具有很好的应用潜力。本文就近年来人们对荧光碳点的研究进行了综述,简述了碳点的特性,重点介绍了荧光碳点应用的最新进展,对碳点发展过程中尚待解决的问题进行总结并对未来发展方向进行了展望。Carbon dots are the most popular nanomaterials in recent years among the nanocarbon family, including fullerene,the carbon nanotube and graphene. This kind of nanomaterial has successfully overcome some defects of traditional semiconductor quantum dots. It is highly evaluated not only for the excellent optical performance and small size effect, but also the great biocompatibility and ease to achieve surface functionalization. Carbon dots can be w idely used in the field of biochemical sensing,fluorescent probes, environmental testing,photocatalytic technology,drug carriers and so on. In this review,the progress made in the field of carbon dots in recent years,especially in latest developments of applications are review ed,the characteristics of carbon dots are outlined,the problems remaining to be solved are summarized and the further advances are prospected.
