Claim Text:
1. A graphene illuminator, comprising: a graphene material forming a plane for providing free electrons; two electrodes respectively disposed on two opposite ends or two opposite lateral sides of the graphene material, and both disposed on the plane of the graphene material; a power supply having a positive terminal and a negative terminal which are respectively connected to the two electrodes, configured to apply, in a first direction, an accelerating electric field to the graphene material; and magnet sets placed on an upper and a lower sides of the plane, configured to generate a magnetic field, wherein a direction of the magnetic field is perpendicular to the plane and is alternately reversed along the first direction; wherein under influence of the accelerating electric field and the magnetic field, the free electrons provided by the graphene material perform a curvilinear motion on the plane and are excited to generate photons.
