METHOD OF MANUFACTURING GRAPHENE USING A PLURALITY OF LIGHT SOURCE

摘要

Disclosed is a graphene manufacturing method using multiple light sources. The graphene manufacturing device according to an embodiment of the present invention comprises the steps of: preparing a substrate coated with a graphite oxide thin film; and irradiating a first light and a second light at least once for each light to the graphite oxide thin film, thereby reducing the graphite oxide thin film. When the first light is irradiated, the first light is linearly collected through an optical device and irradiated to the graphite oxide thin film.
