▎ 摘　　要

Herein, we have reported a new, efficient and one pot methodology for the synthesis of graphene coated silver nanoparticles (GCAgNPs) from an organosilver compound (Silver Acetylide) itself. Synthesis of (GCAgNPs) from silver acetylide has been carried out in anhydrous DMF at 150 degrees C and completed in 1.5 h. Appearance of surface plasmon resonance peak at 426 nm confirms the formation of silver nanoparticles. Presence of graphene over silver nanoparticle has been proved by UV-Vis (pi-pi* transition at 273 nm) and Raman spectrum (G and D band at 1586 and 1408 cm(-1), respectively). TEM analysis of silver nanoparticles shows the formation of spherical shaped nanoparticles with agglomeration to variable extent. Four-point Probe methods has been applied for studying the electrical conductivity of the nanoparticles, which exhibit the conductivity of GCAgNPs to be 4.42 x10(4) S/m. These GCAgNPs will find its application in various fields of photovoltaics.
