摘要

我们采用自底向上的方法制备了比以前更大的等离子体金属纳米颗粒二维阵列，并研究了它们的等离子体特性在传感和光电化学中的应用。从表面增强拉曼散射(SERS)测量中，我们发现直径为50 nm的金纳米粒子阵列比直径为15 nm的金纳米粒子阵列具有更大的增强效果。

Two-dimensional arrays of plasmonic metal nanoparticles prepared by bottom up methods for sensing and photoelectrochemical applications

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.
