The XPS spectra of aluminum phosphate were collected with a VSW HA150 using monochromatic AlKαx-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 O2sregion. The valence band region shows the characteristic phosphate peaks at 13.79 eV and 10.69 eV. The valence band, survey, and the Al2s, Al2p, O1s, and C1score levels are reported.
