International Conference on Emerging Smart Materials in Applied Chemistry (ESMAC-2020) 10-12th August 2020
This paper reports about the research related to Graphene Quantum dots (GQDs) which have been attracted considerable attention in recent years due to the size, edge effects, quantum confinement and heteroatom doping. The doping of graphene based materials can effectively tune their intrinsic properties, including electronic and optical properties, surface and local chemical reactivity.Herein, we were successfully synthesized Cd(II)Cl2 doped GQDs by using a facile, and environment friendly hydrothermal treatment by using less expensive CdCl2 powder and Graphene Oxide (GO) as a precursor materials. All the synthesized materials were characterized by UV-Visible Spectroscopy (UV-Vis), Raman Spectroscopy, and Photoluminescence (PL). The morphological characterizations were confirmed by transmission electron microcopy images (TEM). The hydrothermally synthesized material had a size of 5-20 nm by uniform doping of CdCl2 nanoparticles on graphene sheet.
