XPS Spectra Calcium (Ca) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra.

2016年11月15日 · X-ray Photoelectron Spectroscopy (XPS) indicated the presence of reasonable amounts of hydroxyl groups and oxygen ions in the surfaces of the sample produced with EDA. Radioluminescence (RL) measurements showed that both CaF 2 samples present intrinsic scintillation with emission bands in the UV (293 nm) and in the visible (423 nm) range of the ...

Incorporation of Tb ions into the CaF2 host was confirmed by X-ray diffraction and X-ray photoelectron spectroscopy. Cross-relaxation energy transfer was observed from the photolum...

CaF2 is a promising luminescent host material for a wide range of applications, due to its high transparency, non-hygroscopy, low refractive index, low density, low backscattering efficiency, and...

Here, we report the synthesis of robust hybrid iodinated silica-lipid nanoemulsions (HSLNEs) for use as a contrast agent for ultrasound and X-ray applications. We engineered iodinated silica...

1994年6月1日 · Surface stoichiometry was tested by XPS-microscopy. The spatially resolved observation of line intensities as well as line shifts revealed an effective metallization and oxidation of the surface. Using atomic force microscopy we found evidence for a 3-dimensional island-like formation of Ca aggregates with a size up to 12 i-im diameter.

2011年2月10日 · The initial stages of MBE growth of PbSe on CaF2/Si(111) were studied by in situ XPS. The surface reaction between CaF2 and elemental Se is also studied as a comparison. Ca 2p, F 1s, Pb 4f and Se 3d peaks all shift to lower binding energies (1.2 - 1.6 eV) with increasing PbSe coverage.

XPS 光谱解读. 当样品中含有镁时，检查 Ca2s 谱峰，避免将 Mg KLL 谱峰误判为 Ca2p 谱峰。 Ca 的几种典型化合物之间的化学位移较小（<1eV）。 在化学测定方面的用途有限。 Ca2p 峰具有明显的自旋轨道分裂峰 (Δ 碳酸盐 =3.5 eV)。 在 Ca2p 区域有时可见卫星能量损失特征峰。

1995年12月1日 · X-Ray Photoelectron Spectroscopy (XPS) photoemission lines of some calcium compounds have been measured. The fine structure and position of the Ca 2 p 3 2 line is discussed. The Wagner diagram of the oxygen KLL transitions is presented. The surface composition of some compounds is calculated.

XPS Spectra Fluorine (F) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.
