Description
In this research, graphene quantum dots (GQDs) are made by a simple, fast, cost-effective method using the thermal decomposition of citric acid. By adding different impurities to GQDs and contaminating it with different structures, an attempt is made to increase the luminescence intensity, and also by modifying the surface of these points by polyethylene glycol using the hydrothermal method, an attempt is made to improve their performance. XRD, TEM, HRTEM, FESEM, MAPPING, EDX, PL and UV-Vis analyzes are used to characterize the manufactured nanoparticles and also the feasibility of these materials is investigated from the optoelectronic and electrochemical point of view.
