Highly Pure and Luminescent Graphene Quantum Dots on Silicon Directly Grown by Chemical Vapor Deposition

Abstract

Highly pure graphene quantum dots (GQDs) are directly grown on a silicon wafer by the chemical vapor deposition method. Two fluorescence and two phosphorescence components are emitted from the GQDs. The size-independent luminescence of the GQDs suggests that the luminescence originates from edge defects of the GQDs.
