Abstract Image

In this article, the authors describe synthesis of ligand-free gold nanoparticles (size is deposition time-tunable: 3-10 nm) on nano-structured silver surface via LSPR-promoted decomposition of Me-Au-PPh3.  Gold nanoparticle growth is surface-limited, indicating that the silver surface is essential and that no gold-nanoparticle autocatalysis is taking place.
