在氨丙基三甲氧基硅烷修饰的玻璃基板上，通过简单地将基板在溶胶中浸泡1小时，可以制备出均匀的、单分子层厚的金纳米颗粒阵列(见AFM图像，图)。较长时间的浸泡会导致纳米颗粒形成胶体结构，从而诱导光的二阶偏振。
A uniform, monolayer-thick array of Au nanoparticles are produced on an aminopropylthrimethoxysilane-modified glass substrate by simple immersion of the substrate in the sol for 1 h (see AFM image, Figure). Longer immersion causes the nanoparticles to form colloidal domain structures, which induce a second-order polarization of light.
