Abstract

2D arrays of Au-PNIPAM core-shell nanocrystals were fabricated using convective deposition and spin-coating. The particle density and ordering were studied by AFM. Annealing at 700 °C removes the polymer shell, while retaining a monolayer of well-separated gold nanoparticles. The surface plasmon modes of the colloid monolayers could be measured by spectroscopic ellipsometry.

摘要

使用对流沉积和旋涂法制备了 Au-PNIPAM 核壳纳米晶体的 2D 阵列。通过原子力显微镜研究了粒子密度和有序性。在 700°C 下退火会去除聚合物壳，同时保留单层分离良好的金纳米粒子。通过光谱椭圆测量可以测量胶体单层的表面等离子体模式。
