摘要：

The charge state of Cr and Cu atoms implanted into alpha-Al2O3 and MgO single crystals has been studied by X-ray photoelectron spectroscopy (XPS). The implantation has been performed at 200 and 300 keV to doses of 10(16) to 10(18)/cm2. The implanted Cr atoms prefer to form aggregates in alpha-Al2O3 implanted to high doses while they are preferentially stabilized as Cr3+ in MgO. The presence of Cu2+ has been observed only in MgO and the Cu2+ fraction decreases with higher concentration of implanted Cu atoms.
