Abstract
A method of evaluating quality of graphene using a confocal laser scanning microscope, the method comprising steps of: irradiating with laser light a graphene layer formed on a catalyst layer; detecting a signal of light reflected from the graphene layer; forming a planar image of the graphene layer using the detected optical signal; and analyzing a contrast between graphene and the catalyst layer in the planar image, wherein the graphene layer is continuously formed on the catalyst layer by a roll-to-roll process.
