Defect-band-free luminescence is observed from ZnO nanoparticles fabricated by implantation of 60 keV Zn + ions in silica glass (SiO 2 ) to 1.0 β’ 10 17 ions/cm 2 and subsequent oxidation at 600 Β°C for 1 h. To clarify the mechanism, the samples were evaluated by optical absorption spectroscopy, grazi

Metal-ion implantation followed by thermal oxidation was carried out to fabricate zinc-oxide (ZnO) nanoparticles (NPs) in silica glass (SiO 2 ). A SiO 2 substrate was implanted with Zn + ions of 60 keV up to 1.0 β’ 10 17 ions/cm 2 . In the as-implanted state, the sample shows a strong absorption peak
ZnO thin films on sapphire substrate were fabricated by ion implantation combined with thermal oxidation. A sapphire substrate was implanted with 50 keV zinc ions at 350 Β°C with a fluence of 1.5 Γ 10 17 ions cm Γ2 , then annealed in a tube furnace in oxygen ambient in 2 h at 650 Β°C. Photoluminescenc
Metallic nanoparticles (NPs) embedded in dielectrics display unique structures and new interesting properties, such as peculiar optical properties , size-dependent electronic and magnetic properties , and so on. Owing to their distinct properties, materials composed of discrete metallic NPs have a w
