摘要: As a standard for identification of iron oxides by X-ray photoelectron spectroscopy, Fe 2+ spectra are extracted from mixed Fe 2p 3/2 spectra of Fe 3+, Fe 3+ and metallic states. The peaks of Fe 2+ spectra are all located at binding energy of 708· 5 eV. The width of Fe 2+ spectrum seems to be dependent on crystallinity, and is 2· 2 eV for a bulk crystalline oxide and 2· 9 eV for an amorphous thin film under instrumental condition with FWHM of 1· 3 eV for Au 4f 7/2.
