Abstract

The implantation of 1.5 MeV Ag ions at 1.2 × 10¹⁷ ion/cm² into MgO(100) single crystals produces optical absorption color centers which can be reduced by heat treatment at temperatures above 1000°C. We observed the formation of both F-centers and V-centers. We observed optical absorption due to the formation of silver nanoclusters at heat treatment temperatures above 550°C and due to F-center aggregates at heat treatment above 800°C. Upon further heat treatment, the color centers diminish while absorption due to the Ag nanoclusters is enhanced. Using Mie's theory we confirmed that Ag is in the form of nanoclusters and by using Rutherford backscattering spectrometry (RBS) and ion channeling, we confirmed that these Ag metallic clusters have, in fact, orientations similar to that of the host substrate, MgO. The measured optical absorption due to Ag nanocrystals, 430 nm, is in agreement with the theoretical prediction.
