The Charge State of Iron Ions Implanted Into Sapphire
Keyword(s):
ABSTRACTSingle crystals of α-Al2O3 were implanted with 57Fe+ at room temperature to fluences ranging from 1016 to 1017 ions/cm2. The damage in the implanted zone and the valence states and local environment of implanted ions were studied by transmission electron microscopy, Rutherford backscattering-channelling, and conversion electron Mössbauer spectroscopy. The implanted iron was distributed among the three charge states Fe2+, Fe3+, and Fe°(metallic clusters) with the relative amount of each varying with concentration of implanted iron.
