摘要：
We performed the modification of the size and optical properties of Ag nanoparticles (NPs) embedded in SiO2 by using 500 keV Xe ion irradiation. The results reveal that Xe ion irradiation can eliminate small Ag NPs and promote the growth of large Ag NPs, which significantly enhances the surface plasmon resonance (SPR) absorption at 400 nm. Besides, Xe ion irradiation modifies structures of Ag NPs, resulting in a shoulder absorption peak at around 530 nm. The present work provides an available route to tailor the size and modulate the optical properties of metal NPs. (C) 2012 The Japan Society of Applied Physics
