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.
