Zinc Phosphate (Zn3(PO4)2) by XPS

The XPS spectra of zinc phosphate were collected on a VSW HA 150 using x-radiation. The valence band is dominated by the intense Zn 3d region but one of the two characteristic, phosphate features can be identified in the region below 20 eV binding energy and is consistent with previous data. The reported regions are as follows: survey, O 1s, C 1s, P 2s, P 2p, Zn 3s, Zn 3p, and valence band.
