Core-Satellite Gold Nanoparticle Complexes Grown by Inert Gas-Phase Condensation.

ABSTRACT: Spontaneous growth of complexes consisted of a number of individual nanoparticles in a controlled manner, particularly in demanding environments of gas-phase synthesis, is a fascinating opportunity for numerous potential applications. Here, we report the formation of such core-satellite gold nanoparticle structures grown by magnetron sputtering inert gas condensation. Combining high-resolution scanning transmission electron microscopy and computational simulations, we reveal the adhesive and screening role of H₂O molecules in formation of stable complexes consisted of one nanoparticle surrounded by smaller satellites. A single layer of H₂O molecules, condensed between large and small gold nanoparticles, stabilizes positioning of nanoparticles with respect to one anoth
