dc.description.abstract | We produced Graphene Quantum Dots (GQDs) by electrochemical oxidation of graphite rods
and exposed them to gamma irradiation at a dose of 200 kGy, in the presence of ethylene-diamine. Before irradiation, oxygen was removed from the GQDs dispersion by purging with Ar. These conditions induced both chemical reduction as well as the incorporation of N atoms
in the structure of GQDs. Thus, N-doped GQDs were produced. The morphology of dots was
investigated using atomic force microscopy. UV-Vis and photoluminescence spectroscopy
were used to investigate the optical properties of modified GQDs. The changes in the intensities
of PL emission spectra were studied in the presence of different concentrations of Pd2+ and
pesticide carbofuran. We observed promising results for the application of N-doped GQDs for
non-enzymatic PL detection of selected metal ions and molecules of pesticide. | sr |
