Scholarcy highlights

  • Graphene quantum dot is the latest addition to the nanocarbon materials family
  • GQDs and carbon dots share some similarities, here we exclusively focus on the former
  • Cutting polythiophene by NaOH under hydrothermal condition produces S-doped GQDs which are capable of efficient generation of singlet oxygen, deep red emission and strong light absorption
  • A S-doped GQD has been prepared by hydrothermal treatment of Poly(3-alkylthiophenes), which exhibits deep red emission up to 700 nm
  • GQDs are hybridized with nanomaterials such as NiCo2P2, Ni3S2 and Co3O4 to improve the performance
  • Just like other graphene materials, GQDs can be used to engineer and improve the properties of other functional nanomaterials. In view of their high dispersibility and intrinsic amphiphilic properties, GQDs may serve as a new class of surfactants for many applications
  • It is still expanding, for examples, the recent use of Graphene quantum dots as quasi-homogeneous catalysts for chemical synthesis and conversion and use of GQDs for flexible devices. Just like other graphene materials, GQDs can be used to engineer and improve the properties of other functional nanomaterials. Conceivably, in view of their high dispersibility and intrinsic amphiphilic properties, GQDs may serve as a new class of surfactants for many applications
