DESCRIPTION OF TALK:
Since the discovery of graphene by Geim and
Novoselov in 2004, its exceptional characteristics
such as high electrical conductivity, good thermal
stability and high mechanical stiffness have made it
an indispensable material for many interesting

applications in several areas. However, the zero-
bandgap, low aqueous solubility and low

absorptivity impede the effective employment of
graphene in many applications. To overcome these
limitations, the structural regulations of graphene
have gained significant attention from the
scientists. They have concluded that if the large
graphene sheet is censored into small fragments, it
exhibits interesting characteristics including (zigzag
and armchair) edge sites, quantum confinement
effects and oxygen enriched functional groups. In
pursuit of this, recently, graphene quantum dots

(GQDs) have emerged as a promising quasi zero-
dimensional material of the graphene family.

Owing to their unique set of characteristics
including bright luminescence, ease of synthesis,
favorable biocompatibility, quantum confinement
effect, excellent aqueous solubility, and tunable
bandgap, GQDs have been applied in several
biomedical and optoelectronics applications.
Additionally, since the synthesis methods of GQDs
avert the use of toxic heavy metals and
sophisticated instruments, they have been
considered to be more promising alternate over the
traditional semiconductor quantum dots. Further,
the ability to tailor the desired physical, chemical,
and optical properties of GQDs with ease during the
synthesis process makes them more attractive and
versatile as compared to other allotropes of carbon
such as fullerene, graphene, graphene
nanoribbons, carbon nanotubes, etc.
