Photoluminescent carbogenic dots

A study was conducted for synthesis of supported carbon dots by thermal oxidation of an ion-exchanged NaY zeolite. The study used chemical synthesis and photoluminescence properties of supported carbogenic dots. The study found that spherical carbogenic nanoparticles grafted onto the external surfaces of the zeolite. The study reported that these hybrids has the properties of zeolites with the photoluminescence of the supported carbon dots. The study confirmed that precursor to the carbon dots can be obtained by protanating amine groups of sodium 11-amino-undecanoate with citric acid. The study proved that thermal oxidation of the citrate salt at 300 °C in air produces a modified carbogenic nanoparticels with nominal composition. The study also found that nanoparticles shows a high concentration of carbosylate groups with sodium.
