Abstract

We developed two-dimensional arrays of larger plasmonic metal nanoparticles than before by employing bottom up methods and investigated their plasmonic properties for sensing and photoelectrochemical applications. From surface enhanced Raman scattering (SERS) measurements, we found that the array consisting of gold nanoparticles with the diameter of 50 nm exhibited larger enhancement effects than that of 15 nm.
