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.

2020年2月1日 · Eu 3+ → Eu 2+ and Ce 4+ → Ce 3+ reduction in Au/Ce 0.80 Eu 0.20 O 2 catalyst were systematically studied using in-situ NAP-XPS technique. The reduction of Eu 3+ → Eu 2+ in the ceria, in a hydrogen atmosphere at temperature ≥ 400 …

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...

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....

1995年9月14日 · XPS 3d spectra of Eu in a EuS and a EuF3 tablet: curve a, at the contamination layer; curve b, after removing the oxida- tion layer; curve c, after exposure to the XPS ambient for 3 h; curve d, after long sputtering (saturated regime). For EuF3 curves a, b and c were normalised to the Eu3+3ds/2 photoline.

2006年1月1日 · Eu 3d core-level XPS spectra of EuAg 5, EuPd 2 P 2 and EuCu 5 are reported to show two peaks corresponding to a rearrangement of the 4f-subshells electronic occupation after photoionization; in these compounds europium is exclusively divalent as indicated by Mössbauer spectroscopy and magnetic susceptibility measurements [8], [9], [10], [11 ...

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。

1995年9月1日 · 摘要 Eus 和 EuF 3 粉末样品已成为广泛 XPS 研究的主题。 对于这两种化合物，研究了 Eu 的价态及其稳定性，包括 X 射线剂量、XPS 环境 (UHV) 下的总曝光时间和 XPS 溅射时间。

We found an enhancement of Eu3+ emissions in Eu-doped ZnO nanocrystalline films fabricated by microemulsion method. The Eu3+ emission intensities were increased by reducing annealing temperatures...
