STRESS STATE AND TWIN CONFIGURATION OF SPHEROIDAL SILVER NANOPARTICLES IN GLASS

摘要

Spherical silver nanoparticles embedded in commercial float glass have been fabricated and deformed to prolate ellipsoidal shapes in a multistep procedure that is completed by partial shape relaxation in well-defined regions, so as to obtain microstructuration of dichroic colors. Transmission electron microscopy has been used to monitor not only the size and shape evolution, but also the stress state and defect configuration of the nanoparticles that occur in the course of processing. As our main results, an inhomogeneous lattice strain in the elongated nanoparticles, as well as distinct changes in the defect configuration upon irradiation processing may be stated.
