KDKrishna Moni DekaSDSaikat DasRNRachita Newar

Key Points

  • The aim is to develop a green method for synthesizing blue-emissive graphene quantum dots useful for sensing nitroaromatic compounds.
  • Utilized a modified Tour method to synthesize graphene oxide.
  • Produced graphene quantum dots from synthesized graphene oxide.
  • Assessed the fluorescence for nitroaromatic sensing applications.
  • Successfully synthesized strong blue-emitting graphene quantum dots.
  • Achieved effective detection of nitroaromatic compounds like p-nitroaniline and 2,4,6-trinitrophenol.
  • Demonstrated minimal nanophytotoxicity in analyses.

Abstract

This work introduces an environmentally benign route for producing strongly blue-emissive graphene quantum dots (GQDs) from graphene oxide synthesized via a modified Tour method. GQDs are nanoscale (<10 nm) fragments...
