摘要
Anisotropic Au@SiO2 core-shell nanostructures have been fabricated from CTABr-stabilized Au nanoparticles with a facile synthesis involving a single growth solution. This procedure circumvents tedious surface modification steps and allows for the SiO2 shell thickness to be tuned from 5 to 20 nm by modulating the nanoparticle number density and concentration of silica precursor.
