Synthesis Of Carbon Nanoparticles (C-DOTS) From Natural Dyes And Its Characteristics

Abstract

Carbon nanoparticles (C-dots) are one of the results of the development of nanotechnology that began in 2004. C-dots have the property of being able to fluorescent. C-dots have the potential to replace other nanoparticles, such as quantum dots. C-dots had the same applications as quantum dots but not toxic so that they can be applied more widely in various sectors. C-dots can be synthesized from a carbon-based precursor. The quality of C-dots can be enhanced with carbon-based organic compounds that have conjugated systems and contain heteroatoms, one of which is a natural dye compound. The synthesized method can influence the properties of C-dots. This article reviewed the literature on the synthesis of C-dot from natural plant dye precursors. The results showed that the C-dots synthesized from tannin had better quality than other dye compounds. The solvothermal method improves the quality of C-dots as solvent provides extra functional groups.
