Abstract
Graphene sheets (GSs) can be enfolded to create zero-dimensional graphene quantum dots (GQDs), spined to create one-dimensional carbon nanotubes, or layered to create three-dimensional graphite. Therefore, this chapter is dedicated on different synthesis, applications, and properties of this carbon material in great detail. In addition to inherent physical qualities, the effect of functionalization on GSs and GQDs is assessed through morphological, structural, chemical, and optical properties for enhanced device development. It was observed theoretically and experimentally that surface passivation removes the unwanted surface states within the band gap formed due to dangling bonds and adatoms, thereby raising the band gap values. This chapter also provides an overview on hazardous effect of GQDs and other quantum dots on live human and plant cells via cytotoxicity assay.
