发光碳量子点的合成、性质和应用

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。

Synthesis and Properties of Luminescent Carbon Dots and Its Applications

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.
