Colloidal silver nanoparticles stabilized by a water-soluble triosmium cluster
摘要:
Silver nanoparticles stabilized by the water soluble triosmium cluster Os-3( mu H)(CO)(10)S(CH2)(10)COO]Na were prepared by both photochemical and chemical reduction of silver nitrate. The silver nanoparticles were characterized by UV-Vis spectroscopy and high resolution TEM. The particles obtained by chemical reduction showed remarkable stability. (c) 2005 Elsevier B.V.
