摘要： A graphene quantum dots synthesis method includes fixing a graphene aqueous solution or a graphene oxide aqueous solution on a spin coater to spin the graphene aqueous solution or the graphene oxide aqueous solution, and irradiating a pulsed laser to focus on a graphene aqueous solution or a graphene oxide aqueous solution to generate exfoliation. After a processing period, quantum dots are generated in the graphene aqueous solution or the graphene oxide aqueous solution. Since graphene aqueous solution or graphene oxide aqueous solution does not contain organic chemistry pharmacy, the quantum dots synthesized by the method of the present invention can be produced without pollution. Furthermore, the purpose of simple process, low cost, and time-saved of synthesis can be achieved.

摘要： A method of forming a graphite-based structure on a substrate comprises patterning the substrate thereby forming a plurality of elements on the substrate. Each respective element in the plurality of elements is separated from an adjacent element on the substrate by a corresponding trench in a plurality of trenches on the substrate and each respective element in the plurality of elements has a corresponding top surface. The method further comprises segmentedly depositing a graphene initiating layer onto the top surface of each respective element in the plurality of elements; and generating graphene using the graphene initiating layer thereby forming the graphite-based structure.
