摘要
基于碳量子点具有良好的水溶性、化学惰性、低毒性、易于功能化和抗光漂白性等优异性能,碳量子点和其它的碳纳米材料(如富勒烯、碳纳米管和石墨烯等)同样引起了研究者广泛的关注。碳量子点可以通过很多较为廉价的一步法进行大规模的制备,包括化学氧化法、超声法、微波法和激光烧蚀法等。本文主要介绍了不同碳量子点的合成方法,以及依赖于碳量子点尺寸和波长等性质的发光性能,并且讨论了碳量子点在生物成像、光催化、能量转换/储存、光电子、光限幅和传感器等方面的应用。
Similar to other carbon nano-materials,such as fullerenes,carbon nanotubes and graphene,carbon dots(C-dots) have inspired intensive research attention according to their superior solubility in water,chemical inertness,low toxicity,easy functionalization and resistance to photobleaching.C-dots can be produced inexpensively through lots of one-tep approaches on a large scale such as simple chemical oxidation reactions,ultrasonic treatment,microwave method and laser ablation strategy,etc.In this review,we mainly introduced different synthesis approaches of C-dots,size-and wavelength-dependent luminescence emission property,etc.Furthermore,applications of C-dots in photocatalysis,energy conversion/storage,bioimaging,optoelectronics,optical limiting,sensors,etc.were also discussed.
