Synthesis of Carbon Dots from Orange Carrot Juice

Abstract

In this research. scanning Electron Microscopy (SEM) image confirmed that CDs are almost
spherical in shape and the size is around 6.40 – 25.76 nm. The energy-dispersive X-ray (EDX)
spectrum showed the existence of carbon in the samples. The Fourier-transform infrared
(FTIR) spectrum of carrot extract (CE) and CDs is explained that the -C=O peak was found in
1740 and 1650 cm-1 in the CE, but it is completely lost in CDs. This result indicates that the
carbonyl group has undergone carbonization and producing luminescent CDs
