Abstract
Ordered arrays of metal nanoparticles were prepared by a micellar route based on the self-assembly of a diblock copolymer to micelles. Taking advantage of this route, the size and interparticle spacing of the metal nanoparticle arrays were tuned effectively by varying the chain length of the ramphiphilic diblock copolymer, the amount of metal salt loading, and the drawing velocity during dip-coating process. As an application example of Au nanoparticle arrays, the characteristics of localized surface plasmon (LSP) were studied by varying the interparticle spacing.
