X-ray Photoelectron Spectroscopy Study of BaWO_4 and Ba_2CaWO_6

Abstract

XPS reference spectra for Ba_2CaWO_6 and BaWO_4 are presented, including high resolution spectra of the Ba 3d, W 4f, C 1s, Ca 2p, and O 1s lines. The peak locations and full widths at half maximum are also given. The binding energies of the Ba 3d and W 4f lines are 0.7 eV higher for BaWO4 than for Ba_2CaWO_6. The Ca 2p spectrum contains two sets of Ca 2p doublets that were attributed to Ba_2CaWO_6 and CaCO_3.
