2024年8月1日 · XPS analysis performed on Eu 2 O 3 confirms the presence of oxygen vacancies. Our SQUID measurement reveals that Eu 2 O 3 unveil a strong ferromagnetic character which arises due to exchange between free localized charge carriers of oxygen vacancies.

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.

2014年9月30日 · Crystalline hexagonal phase Eu (OH) 3 nanorods were prepared by a hydrothermal method, and cubic phase Eu 2 O 3 nanorods were obtained by a post-annealing treatment, after which their physicochemical properties were fully characterized by X-ray diffraction (XRD) crystallography, scanning electron …

Europium oxide (Eu2O3) had been extensively studied for its potential application in photonics, transistor devices, in resistive random access memory devices, white-light-emitting,...

The two oxidation states were detected as EuCl²⁺ and EuCl³⁺ species using XPS analysis, essentially Eu (II) and Eu (III) oxidation states, respectively. The TL glow curve consists of major ...

2019年2月25日 · Trioxide compounds of the critical rare earth elements Eu and Nd were characterized using x-ray photoelectron spectroscopy after heating to remove surface carbonate and greatly reduce the contribution from surface hydroxide. High-resolution 3 d and 4 d spectra of the elements are presented along with O 1 s spectra.

本文报告了铕 (III) 化合物的 XPS 结合能数据库，其中 Eu 阳离子具有多种化学环境：简单氧化物 Eu2O3、Eu 与有机草酸盐、乙酰丙酮化物或无机硫酸盐、硝酸盐、碳酸盐配体的混合氧化物。

2015年10月1日 · XRD and Raman spectroscopy reveal that the grown film is single phased and belongs to the cubic structure of Eu2 O 3. XPS study of the Eu1.92 Fe 0.08 O 3 film shows that Fe exists in Fe 3+ ionic state in the film. The film exhibits magnetic ordering at room temperature.

2012年1月26日 · The XPS results demonstrate the Eu 2 O 3 microwires possess many oxygen vacancies. Magnetism measurement of Eu 2 O 3 microwires indicates that the reciprocal magnetic susceptibility does not satisfy a simple Curie–Weiss law, which is different from the bulk Eu 2 O 3 with typical paramagnetism.
