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. Herein, a thorough study of a graphene quantum dot made of 96 carbon atoms in a D2h symmetry is reported. In particular, experiments at the single‐molecule level reveal that this graphene quantum dot structure is a bright and photostable 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. [ABSTRACT FROM AUTHOR]
