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 โข 10 17 ions/cm 2 and subsequent oxidation at 600 ยฐC for 1 h. To clarify the mechanism, the samples were evaluated by optical absorption spectroscopy, grazi
