Abstract

Al+ ions have been implanted in silica glass at an acceleration energy of 200 eV and doses ranging from 1×10 13 to 1×10 17 ions cm -2. Infrared reflection spectra and ultraviolet, visible, and near-infrared absorption spectra have been measured. It was found that refractive index of silica glass increased by 6%-10% after implantation of 1×10 17 Al + ions cm -2. It was deduced that this refractive index change is caused by the formation of Si-Si homobonds. but not by the decrease in Si-O-Si bond angle which leads to compaction.
