Phase Separation on Mixed-Monolayer-Protected Metal Nanoparticles: A Study by Infrared Spectroscopy and Scanning Tunneling Microscopy
2007
Abstract
Mixed monolayers, which on flat surfaces phase-separate into randomly shaped domains, spontaneously form ordered rings of alternating composition when assembled around the core of a monolayer-protected gold nanoparticle (see figure). It is shown that it is possible to use infrared spectroscopy, a simple and common technique, to prove the existence of these phase-separated domains on nanoparticles.
