Nanocrystalline textured EuO thin films are prepared by an oxygen loss process from a pure Eu2O3 bulk ceramic target through pulsed laser deposition in vacuum at room temperature. X-ray diffraction...

2006年1月1日 · We are studying interaction mechanisms between an aqueous Eu (III) and an alumina surface, in the presence of an inorganic or organic complexing agents [1]. Our approach is based on the combination of spectroscopic methods as X-ray photoelectron spectroscopy (XPS), and sorption experimental data interpreted with thermodynamic.

2024年8月1日 · XPS is a useful technique to quantify the chemical compositions and analyse the valence states of Eu 4d and O 1 s in Eu 2 O 3 nanoparticles. The core level electronic nature and chemical state of Eu is determined by Eu 4d region of the XPS spectra.

We report an inverted and multilayer quantum dot light emitting diode (QLED) which boosts high efficiency by tuning energy band alignment between charge transport and light emitting layers.

2004年5月1日 · In this paper, a new luminescent europium polydimethylsiloxane complex, Eu (III)-PDMS, was synthesized and characterized by ultraviolet-visible absorption spectrometry (UV), Fourier transform infrared absorption spectrometry (FT-IR), X-ray photoelectron spectroscopy (XPS) and fluorescence spectroscopy.

2009年3月24日 · Results of an X-ray photoelectron spectroscopy (XPS) analysis showed that Eu(III) was chemically present within the near-surface of TiO 2 due to the formation of ≡SOEu and ≡SOHAEu complexes. An extended X-ray absorption fine structure (EXAFS) technique was applied to characterize the local structural environment of the adsorbed Eu(III), and ...

Eu 3d 3/2 and 3d 5/2 XPS peaks are shown as a function of Eu content in at %. The position of all prominent peaks are indicated in the figure in terms of their absolute binding energy in eV....
