Europium oxide as a perfect electron spin filter
… have at best a spin polarization P-50%. Europium monoxide is a novel material capable of generating a highly spin-polarized current when used as a tunnel barrier. EuO is both a Heisenberg ferromagnet (Tc=69 K) and a semiconductor. Exchange splitting of the conduction band creates …

Transition Metal Complexes Anchored on Europium Oxide Nanoparticles
… absorbing and emitting properties. Lanthanide oxides such as europium oxide absorb light as well and exhibit strong luminescence and long lifetimes. The optical properties of these materials were significant especially in solar energy utilization schemes and optical applications. Energy …

Nonlinear Luminescence Quenching in Eu2O3
Nonlinear luminescence quenching has been documented in numerous systems such as organic crystals, rare earth insulators, laser materials, semiconductors, and phosphors. In each of these systems nonlinear luminescence quenching occurs under conditions of high excitation density from interactions …

Synthesis and characterisation of pillared clay catalysts for hydro-cracking of heavy liquid fuels
… of chromia pillared montmorillonite and tin oxide pillared laponite clay catalysts, as well as new pillared clay materials such as cerium and europium oxide pillared montmorillonites were synthesised. Methods included both conventional ion exchange techniques and microwave enhanced methods to …

Probing interfacial electronic structure in quantum materials using stem cathodoluminescence spectral imaging
… the two-dimensional electron gas formed between europium oxide (EuO) and potassium tantalate oxide (KTaO3, KTO) illustrates how interfacial chemistry and symmetry breaking drive the superconductivity. These two systems motivated the structure-property relation study here that is simultaneously …
