It is demonstrated that the nanoparticle size can be controlled from 3 to 10 nm by changing the heat-treatment temperature and/or the stabilizing agent in the presence of tetraoctylammonium bromide. The Figure shows 6.8 nm particles heat-treated at 190 °C. 关键词: Nanostructured materials;Particle size analysis;Gold;Heat treatment;Van der Waals forces;Coulomb blockade;Superlattices;Thermodynamics;Optical devices;Transmission electron microscopy;Atomic force microscopy;Electron tunneling;Nanoparticles;Surface plasmon absorption
