UV-visible absorption measurements of re-dispersible silver particles that were obtained by reduction of silver myristrate (product-IV) and silver nitrate (product-I) showed surface plasmon resonance absorption peak at 400 nm. The powder XRD pattern of fcc zero-valent silver resulted in diameters in the range of about 25-30 nm. TEM analysis showed particle diameter similar to that was observed by the XRD. FTIR spectroscopy revealed that the organics from the carboxylate group are retained by the nano-particles in case of product-IV however, presence of TOP is observed in product-I. It is found that when silver nitrate is reduced by TOP, spherical silver nano-particles with poor redispersity are formed but extended heating results in formation of long silver rods of micrometer size however, the re-dispersible nano-particles are easily formed when silver carboxylates are reduced by TOP.</p>10aChemical synthesis10aNanocrystalline10anoble metal10aXRD1 aCharan, Shobhit1 aSingh, Narendra1 aKhanna, P., K.1 aPatil, K., R.  uhttps://library.ncl.res.in/content/direct-synthesis-nanocrystalline-silver-reaction-between-silver-carboxylates-and-n-0
