The bridging and nonbridging oxygen signals of glasses are well resolved and now can be accurately measured by XPS without resorting to ad hoc fitting procedures. All O 1s spectra of silicates collected so far are somewhat asymmetric to the high binding energy side of the peak, a characteristic...
Interpretation of XPS spectra Interpretation of O1s spectra is not straightforward. Apart from metal oxides, the O1s binding energy of many compounds and species falls within a very narrow range. O1s peaks tend to be broad, with multiple overlapping components. Components due to wa...
结合P和O XPS谱图及元素含量分析,结果表明F-Al-O物种与P之间的化学键合作用可能是稳定亚稳态F-Al-O物种的有效途径。 Figure 3 High-resolution Al 2p (a), P 2p (b), O 1s (c) XPS spectra of fresh and spent AlPO4; ...
SPECTRAXPS spectra of nine model polymers containing oxygen functional groups are studied. The measured O 1s binding energies were 532.8 eV for ether and alcohol oxgens, 532.2 eV for ketone oxygens and 532.2 and 533.7 eV for the carbonyl- and ether-type oxygens in ester groups, respectively....

The O1s core level shifts between an isolated H2O molecule and the Zn oxo compounds or ZnO, as well as between oxygen atoms in bulk ZnO and at various ZnO surfaces, can be understood by means of Madelung potentials and electronic relaxation or screening. XPS spectra were calculated for ...
aThe presence of surface oxygen vacancies was evaluated by studying the O1s XPS spectra, as shown in Fig. S3. The spectra were deconvoluted into three component peaks, assigned to lattice oxygen (OI, _529 eV), surface oxygen, OH groups and oxygen vacancies (OII,531 eV), and adsorbed water...
