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.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

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 …

2024年8月1日 · With the help of X-ray photoemission spectroscopy, the electronic structure of Eu 2 O 3 nanoparticles is investigated. This revealed the formation of oxygen vacancies as well as the presence of the Eu cation in the two valence states + 2 and + 3.

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

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.

By combining a 410 nm near-ultraviolet chip with the blue phosphor developed in the present work, a red phosphor (SrxCa1-xAlSiN3:Eu²⁺), and a yellow-green phosphor (Y3Al5-xGaxO12:Ce³⁺), a pc-WLED...
