Figure 1: Structural properties of giant colloidal silver single crystals.
From: Giant colloidal silver crystals for low-loss linear and nonlinear plasmonics
(a,b) Optical microscopy (OM) images of colloidal Ag single crystals in solution and on an indium-tin-oxide-coated glass substrate, respectively. (c) Scanning electron microscopy (SEM) image of Ag crystal. Part of the Ag crystal sidewall was modified by FIB milling. (d) XRD wide-scan pattern shows only the Ag (111) peak. The FWHM of the Ag (111) peak determined by high-resolution XRD is <0.05°, which is close to the instrument limit. (e) High-resolution TEM image of Ag crystal. The TEM sample was prepared by FIB milling from the top facet of Ag crystal. (f) Selected area diffraction pattern obtained from the TEM image area shown in e.
