We have studied photoluminescence emission and optical absorption from platinum nanoparticles (Pt-nps) embedded in a silica matrix obtained by ion implantation. The Pt ions were implanted at 2MeV and the nanoclusters were nucleated after thermal treatment at 600, 800, and 1100°C under two different atmospheres: argon gas and a reducing atmosphere compound of H2 and N2. The luminescent spectrum is...
Cu nanoparticles (NPs) have been fabricated in Si 3 N 4 /Si by 45keV Cu ion implantation at a dose of 1×10 17 cm −2 , and followed by thermal processing at 500–700°C in air. Techniques, such as atomic force microscopy and X-ray diffraction are used to confirm the formation and evolutions of Cu NPs. The surface plasmon resonance of Cu NPs has been investigated by reflection...
