The TaN bare substrate (red line) XPS spectrum shows peaks at binding energies around 230.4 eV and 242.5 eV, which are distinctive of the 4d 5/2 and 4d 3/2 states of partially oxidized TaN, such...

Novel tantalum (Ta) and chitosan (CS)-doped CuO nanorods (NRs) were synthesized using a single step co-precipitation route. Different concentrations (2 and 4%) of Ta were used in fixed amounts of...

2005年9月30日 · X-ray photoelectron spectroscopy (XPS) is a very suitable method to analyse these interfacial regions. Changes in the interface chemistry can be detected by XPS and watching for chemical shifts of the photoelectron peaks.

Interpretation of XPS spectra Ta4f region has well separated spin-orbit components (Δmetal=1.92eV). Loss feature for Ta metal appears at ~33eV and ~38eV for Ta 2 O 5 .

XPS spectra (Ta4d, O1s, C1s) for a polished Li 7 TaO 6 pellet (a) before and (b) after exposure to metallic Li. The electrochemical stability window of Li 7 TaO 6 was evaluated using cyclic voltammetry (CV) with a semiblocking cell configuration (Au-Li 7 TaO 6 -Au/Li).

2019年4月15日 · The XPS results demonstrate the existence of Sm 3+ and Sm 2+ ions in SmNbO 4 and SmTaO 4. The Sm 3d 5/2 peak consists of strong features characteristic of Sm 3+ (1083.0 eV) with electron configuration (4f 5 ) and Sm …

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

2012年2月25日 · 本文采用XPS分析方法，研究了Tini合金镀 钽层表面的成分和化学价态的变化，因为镀钽层表面成分和化 学价态与镀钽Tini合金的抗腐蚀性能和生物相容性密切相关。

The absorption band in XPS Ta4f and Ta4d spectra shifted to the lower energy region by the value ΔE = 0.65 eV, and in the region of the Ta4d edge by the value ΔE = 0.55 eV relative to Ta 2 O 5, indicating that tantalum ions have the oxidation degree Ta(+5-δ). The results indicate that doping pyrochlores with magnesium ions does not ...

43 High-resolution XPS of Ta 4f in TaNOC-2 and TaNOC-3 display similar species that contain Ta-O and Ta-N (Supporting Information: Figures S2A and S3A). These two species are also verified in Ta...
