Investigation of Rod‐shaped Single Graphene Quantum Dot
Résumé
In recent years, there has been a resurgence of interest in graphene quantum dots ( i.e. large polycyclic aromatic hydrocarbons) in particular due to their interesting properties as single quantum emitters. Here, we report on a thorough study of a graphene quantum dot made of 96 carbon atoms in a D 2 h symmetry. In particular, experiments at the single molecule level reveal that this graphene quantum dot structure is a bright and photo‐stable single photon emitter at room temperature. Finally, a statistical study of the emission wavelength as a function of the graphene quantum dot concentration highlights the high purity and degree of control on the samples.
