石墨烯量子点的制备及应用

石墨烯量子点(GQDs)作为石墨烯家族的最新一员,除了继承石墨烯的优异性能,还因量子限制效应和边界效应而显现出一系列新的特性,引起了化学、物理、材料和生物等各领域科研工作者的广泛关注。GQDs的制备方法通常分自上而下和自下而上的方法。对其各种制备方法和应用分别进行了介绍,并结合各种应用对GQDs的要求给出了制备方法的建议。指出了GQDs研究中存在的问题及发展方向。

Preparation and Application of Graphene Quantum Dots

Graphene quantum dots(GQDs) as a new member of the graphene family,in addition to inheriting the excellent properties of graphene,show a series of new features due to quantum confinement effect and boundary effect,so it has caused the attention of chemical,physic,material and biological researchers.In this paper,various preparation methods and application of graphene quantum dots were introduced.At last,existing problems in the research of GQDs were pointed out as well as development direction.
