The isolation of carbon dot fractions obtained at different stages of hydrothermal synthesis from citric acid and ethylenediamine is discussed. Gel electrophoresis was used for the isolation, resulting in the isolation of up to five different carbon dot fractions formed at the same stage of hydrothermal synthesis. The optical properties of each isolated fraction were analyzed using photoluminescence spectroscopy, photometry, time-resolved spectroscopy, and IR absorption spectroscopy. Keywords: carbon dots, fractionation, electrophoresis, fluorophores.
