Synthesis of Graphene Quantum dots from the fresh leaves extract of Cynodon Dactylon and its Photoluminescence studies

Abstract

The current research is mainly focused on the synthesis of graphene quantum dots from the fresh extracts of Dhruva Grass (Cynodon Dactylon) by a One-pot, facile, solvothermal method at 60°C for 1 hr using a solvent mixture of Methanol and acetone in a ratio of 1:1. The high resolution transmission electron microscope image showed the formation of Graphene quantum dots with average size of 3-5 nm with the fluorescent quantum yield of 49.1%.
