Aluminum Phosphate by XPS

The XPS spectra of aluminum phosphate were collected with a VSW HA150 using monochromatic Al Kα x-radiation. Monochromatic radiation provides a distinct clarity to the rich peak structure in the valence band of aluminum phosphate due to the absence of interfering x-ray satellites from the intense O 2s region. The valence band region shows the characteristic phosphate peaks at 13.79 eV and 10.69 eV. The valence band, survey, and the Al 2s, Al 2p, O 1s, and C 1s core levels are reported.
