A synthesis and patterning process of luminescent graphene quantum dots (GQDs) is highly desirable in applications to industrial- and bio-fields. In this paper, a novel strategy to obtain GQDs is proposed and demonstrated by an ion-beam assisted chemical vapor deposition (CVD). Ion-beam irradiation...
