Recent Article Published: Green Synthesis of Fluorescent Carbon Nanoparticles and Investigation of the Effect of Passivating Agent Molecular Weight on Nanoparticle Properties

In this research article , synthesis of fluorescent carbon nanoparticles from a natural carbon source, carob molasses, was investigated. To this end, thermal synthesis methodology as a green synthesis method with the easşekil2iness to carry out Black Hat Seo and being economical was followed and polyethylene glycol of different molecular weight (PEG Mn: 300~20000) was used as surface passivating agent.  Synthesized fluorescent carbon nanoparticles (FCNPs) were then characterized by field emission scanning electron microscope (FE-SEM), transmission electron microsocope (TEM), X-Ray Diffraction Analysis (XRD), UV spectrophotometer, fluorescence spectrophotometer, dynamic light scattering (DLS) methods. Results showed that surface properties of nanoparticles and fluorescent properties as a result were found to be determined by the molecular weight of the passivation agent. Moreover, hydrodynamic size of nanoparticles with core diameter measured as 10-15 nm was also found to be increased with increased polymer Mn.
