Abstract: Ion implantation was used to produce nanostructures in MgO, Al2O3 and SiO2. Optical absorption spectra show surface plasmon resonance bands characteristic of the implanted metal ions. Upon annealing in reducing atmospheres the optical response of metal nanostructures changes what is related directly to their morphology, shape and size.
