The optical properties of metallic tin nanoparticles embedded in\nsilicon-based host materials were studied. Thin films containing the\nnanoparticles were produced using RF magnetron sputtering followed by ex situ\nheat treatment. Transmission electron microscopy was used to determine the\nnanoparticle shape and size distribution; spherical, metallic tin nanoparticles\nwere always found. The presence of a localized surface plasmon resonance in the\nnanoparticles was observed when SiO2 and amorphous silicon were the host\nmaterials. Optical spectroscopy revealed that the localized surface plasmon\nresonance is at approximately 5.5 eV for tin nanoparticles in SiO2, and at\napproximately 2.5 eV in amorphous silicon. The size of the tin nanoparticles in\nSiO2 can be varied by changing the tin content of the films; this was used to\ntune the localized surface plasmon resonance.\n
