Title: Raman spectroscopy of bottom-up synthesized graphene quantum dots: size and structure dependence

Journal Article · · Nanoscale
DOI: https://doi.org/10.1039/C9NR05345J · OSTI ID:1570627

Graphene quantum dots (GQDs) have attracted significant interest as synthetically tunable optoelectronic and photonic materials that can also serve as model systems for understanding size-dependent behaviors of related graphene structures such as nanoribbons. Here, we present a Raman spectroscopy study of bottom-up synthesized GQDs with lateral dimensions between 0.97 to 1.62 nm, well-defined (armchair) edge type, and fully benzenoid structures. For a better understanding of observed size-dependent trends, the study is extended to larger graphene structures including nano-graphene platelets (>25 nm) and large-area graphene.
