Electronic properties of graphene quantum dots (GQDs) constitute a subject ofintense scientific interest. Being smaller than 20 nm, GQDs contain confinedexcitons in all dimensions simultaneously. GQDs feature a non-zero band gap andluminesce on excitation. Tuning their electronic structure is an attractivegoal with a technological promise. In this work, we apply density functionaltheory to study an effect of neutral ionic clusters adsorbed on GQD surface. Weconclude that both HOMO and LUMO of GQD are very sensitive to the presence ofions and to their distance from the GQD surface. However, the alteration of theband gap itself is modest, as opposed to the case of free ions (recentreports). Our work fosters progress in modulating electronic properties ofnanoscale carbonaceous materials.
