Investigation of luminescence quantum yields of carbon dots synthesized from ethylene glycol, citric acid and berries

Abstract

The paper describes the investigation of luminescencequantum yields of carbon dots (CDs) synthesized from different carbon precursors. In the synthesis, were used precursors such as ethylene glycol (EG), citric acid (CA) and juice of berries grown in the Far North.Synthesis was carried out by two methods of hydrothermal synthesis using microwave and a polytetrafluoroethylene autoclave. The photoluminescence quantum yields of these CDs were determined to befrom 0.008 to 0.46. The obtained CDs can be used to develop detectors for chemical elements and various optoelectronic applications, as well as in biomedicine and bioimage production.
