Abstract

The variation of the optical properties of embedded metallic nanoclusters induced by changes of their morphology is investigated by an approach combining electron microscopy, grazing incidence small angle X-ray scattering and transmission measurements. For this purpose, silver nanoclusters with various shapes (from prolate to oblate) and embedded in an amorphous Si3N4 matrix are elaborated by ion beam sputtering using either a co-deposition process or an alternate sputtering. Moreover, a post-irradiation with Ar+ ions (at different fluences and low incident energy of 75–100 keV) is used to complement the fabrication process in order to tailor the nanoclusters shape. Prolate and oblate nanoclusters become then more spherical leading to a spectral shift of their surface plasmon resonance.
