DEVELOPMENT OF FACILE SYNTHESIS MEHTOD FOR CHEMICALLY FUNCTIONALIZED GRAPHENE QUANTUM DOTS AND THEIR APPLICATIONS.
- Abstract
- This study has demonstrated the developing different types of functionalized graphene quantum dots (GQDs) by facile, green and cost effective bottom-up strategies. Characteristics of the as-prepared GQDs were investigated by several measurements, transmission electron microscope (TEM) , atomic force microcope, fluorescence , raman, XPS and FTIR spectroscopy. The modified GQDs possessed high quality of graphitic materials as well as interestingly tunable properties. The chemical functionalization significantly enhanced new disorder structures or functional groups on the surface of the GQDs, thus leading to effectively generate active sites or tailor electronic structures for specific purposes. Therefore the wide range applications have made based on unique properties of these functionalized GQDs. In particular, all these obtained GQDs have shown excellent practical potential, greatly promising an effective alternation for synthesizing and employing GQDs in reality
