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.
