摘要
碳点是一类新兴的零维碳纳米光学材料,在众多领域备受关注.近红外光相比于可见光具有更深的组织穿透能力和更低的散射,在生物成像等领域优势明显.随着科研人员的探索,碳点发光带隙的调控从最初的蓝紫光向长波长不断红移.近年来,近红外波段吸收/发光的碳点也相继被报道.本文以本课题组在近红外碳点领域的一系列工作为基础,总结评述了近红外碳点的制备策略及多方面应用的最新进展,并对未来的发展方向进行了展望.
Carbon dots(CDs)are an emerging class of zero-dimensional carbon nano-optical materials that are as promising candidates for various applications.Compared with visible light,near-infrared light has deeper tissue pene⁃tration and lower scattering,giving it obvious advantages in fields such as biological imaging.Through the exploration of scientific researchers,the optical band gap of CDs has been continuously regulated and red-shifted from the initial blue-violet light to longer wavelengths.In recent years,CDs with near-infrared absorption/emission have been gradually reported.Based on a series of works by our research group on the near-infrared carbon dots,this review summarizes and reviews the latest progress in preparation strategies and applications of near-infrared carbon dots,and prospectively outlines the future development directions.
