Gd 3d high-resolution XPS spectra consist of a Gd 3d spin−orbit doublet located at 1222.6 and 1198.2 eV, which is attributed to the Gd 3d 3/2 and Gd 3d 5/2 oxidation states, and...

2015年1月1日 · Gd 3d, O 1s and impurity C 1s XPS peaks were commonly observed for Gd(OH) 3 and Gd 2 O 3. On the basis of the TPR experiment, it was found that the reduction of bulk oxygen of Gd 2 O 3 occurred at 790 °C. The fundamental properties revealed from the present study are useful for the development of Gd hydroxide and oxide nanorods.

2020年2月28日 · Surface chemical composition of gadolinium niobate GdNbO 4 (GNO) and tantalate GdTaO 4 (GTO) thin films was examined by X-ray photoelectron spectroscopy (XPS). XPS spectra confirmed Gd3+ and Nb 5+ or Ta 5+ valence states in films. The Gd 3d doublet was shown with energy difference equal Δ = 32.7 eV.

Collect principal Gd (4d) peak as well as Gd (3d). Long time exposures (high dose) to X-rays can degrade various polymers, catalysts, high oxidation state compounds; During XPS analysis, water or solvents can be lost due to high vacuum or irradiation with X-rays or Electron flood gun

2019年8月1日 · The effects of Gd 3+ ion and Gd 2 O 3 on the structure and optical property of TiO 2 were studied by XRD and UV-vis DRS. Specific surface area was determined by Brunauer-Emmett-Teller (BET) method. The morphology and elemental composition were characterized by SEM-EDS. XPS was used to determine the surface compositions and chemical character of ...

Core level high-resolution XPS spectrum of the Gd 3d (b) and O 1s (c) energy levels. Ultra-small crystals of undoped and Eu-doped gadolinium oxide (Gd2O3) were synthesised by a simple, rapid...

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

The X-ray photoelectron spectroscopy (XPS) spectra of Gd 3d 5/2 and Gd 2 O 3 3d 5/2 peaks are located at 1,186.73 and 1,189 eV, respectively ( Figure 5), which proves a Gd-rich Gd 2 O...

2011年2月15日 · We synthesize ultra small (1–3 nm) Gd 2 O 3 nanoparticles by a facile method which requires lower temperature and shorter synthesis time. These nanoparticles induce phosphorescence from ethylene glycol and citric acid.

This paper presents the X-ray Photoelectron Spectroscopy (XPS) analyses of the electron beam degraded and undegraded Gd2O2S:Tb3+ phosphor powder. The XPS data was collected from Gd2O2S:Tb3+ phosphor powders before and after electron beam degradation. The data confirms the presence of Gd2O3 and Gd2S3 from both the degraded and undegraded powders.
