For pure BaTiO3, the Ti XPS spectra is a strong feature and reveals a doublet Ti2p3/2 (binding energy 458 eV) and Ti2p1/2 (binding energy 464 eV) arising from spin orbit-splitting energy ...

1980年8月1日 · XPS investigations on Ba and BaO have been performed to measure characteristic differences between the spectra of Ba and BaO. A typical difference in satellite structure is related to different plasmon losses. The shifts in XPS-peak positions are rather small.

2024年7月22日 · We report a detailed investigation into the electronic structure and chemical properties of polycrystalline BaZrS 3 perovskite powder by X-ray photoelectron spectroscopy, complemented by an analysis of its long- and short-range geometric structures using X-ray diffraction and X-ray absorption spectroscopy.

Powder and ceramics of barium titanate prepared by the citric process were studied by x-ray photoelectron spectroscopy (XPS). Spectra of C1s, O1s, Ti2p, Ba3d, and Ba4d levels are analyzed in...

Ba0.5Sr0.5TiO3 (BST) thin films grown on Si by an in situ ultraviolet-assisted pulsed laser deposition (UVPLD) technique exhibited significantly higher dielectric constant and refractive...

2005年4月15日 · X-ray photoelectron spectroscopy is employed to study inner-shell core-level binding energies Eu 4d, Ti 2p and O 1s, Ba 3d for new single-phase Ba 1−x Eu x TiO 3 (0.1 ≤ x ≤ 0.4) samples prepared by solid state reaction at 4.0 GPa and 1090 °C.

XPS能够检测元素的不同化学状态，通常认为当原子失去电子的时候（即元素处于高价状态），轨道上电子的结合能会增加，表现在XPS谱峰上，就是图谱会向高结合能端偏移（如图1所示）；相反，当原子得到电子的时候（处于负价态），轨道电子的结合能会降低（如图2所示）。 图1 正价元素电子结合能的变化 [1] 图2 负价元素电子结合能的变化 [1] 案例分析—氧空位XPS分析. O 2- 离子是2p轨道完全填满电子的状态，是最稳定的状态，所以当一个电子转移走了之后（即出现了 …

XPS 光谱解读. Ba3d 区域具有明显的自旋轨道分裂峰 (Δ=15.3 eV)。 在 Ba3d 区域 791 eV 和 806 eV 处可能观察到能量损失特征峰。 Ba3d 峰和 Co2p 峰明显重叠。 虽然 Ba3d 峰与 Co2p 峰干扰严重，但 Ba3d 自旋轨道分裂峰的强度比为 3:2 而 Co2p 的强度比为 2:1。

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.
