Optical properties of Au nanoparticle composites and a grid structure of Cu nanoparticle composite were studied. Negative ion implantation was applied to synthesize Au and Cu nanoparticles in amorphous SiO2 and Al2O3. Au nanoparticles were embedded within a depth of 30 nm by 60keV Au− implantation. The surface plasmon resonance (SPR) of Au:SiO2 and Au: Al2O3 composites shifted to red and to blue,...
Optical absorption and nonlinear optical response were studied for metal nanoparticle composites. Negative ions, Cu - , Au - , Ag - , Ta - and W - with 60keV were applied for implanting into amorphous(a)-SiO 2 The absorption spectra of various metal ion implanted a-SiO 2 showed a surface plasmon peak resulting from formation of nanoparticles...
