Synthesis of Well-dispersed Copper Nanoparticles by L-ascorbic Acid in Diethyleneglycol

摘要：

　　Metallic copper nanoparticles were synthesized in the presence of poly(N-vinylpyrrolidone) (PVP) as the capping agent and L-ascorbic acid as the reducing agent in diethyleneglycol (DEG) solvent.The obtained copper nanoparticles were characterized by scanning electron microscopy (SEM),energy dispersive spectroscopy (EDS),transmission electron microscopy (TEM) and X-ray diffraction (XRD).The EDS and XRD results showed that the resultant particles were confirmed to be crystalline Cu with a face-centered cubic (fcc) structure.It was also observed that the diameter of obtained copper particles ranging from 80 to 120nm via SEM and TEM.
