| Curve-fitted Sb 3d and overlapping O 1s XPS spectrum. |
Sb 3d5/2 -3d3/2 doublet separation: 9.34 eV [2].
Sb 3p3/2: 767 eV
Sb 2p1/2: 813 eV
Sb 3s: 944 eV
Sb 4d: 33 eV
Sb 4p: 99 eV
Sb 4s: 153 eV
Notes:
A) Sb 3d5/2 overlaps with the O 1s spectrum. One needs to fit and constrain the Sb 3d5/2 and Sb 3d3/2 peaks using the 3d3/2 peaks as a guide. Remaining area in the 3d5/2 area will be due to O 1s signal (see spectrum above).
B) Sb2O3 standard samples has Sb 3d5/2 at 530.1 to 530.3 eV. Sb2O5 standard sample is at 530.9 eV [3].
C) Sb2S3 standard sample (Stibnite mineral sample) has Sb 3d5/2 peak at 529.6 eV and S 2p3/2 at 161.2 eV [3].
D) KSbO3 standard sample has Sb 3d5/2 peak at 530.7 eV and K 2p3/2 at 292.8 eV [3].
