Lanthanide-doped nanoparticles are widely investigated for their optical properties. However, the sensitivity of the lanthanide ions' luminescence to the local symmetry, useful when investigating structural environments, becomes a drawback for optimized properties in the case of poorly controlled crystallinity. In this paper, we focus on β -NaYF4 n...

Lanthanide elements exhibit highly appealing spectroscopic properties that are extensively used for phosphors applications. Their luminescence contains precise information on the internal structure of the host materials. Espe-cially, the polarization behavior of the transition sublevel peaks is a fingerprint of the crystal phase, symmetry, and defe...

Nowadays, intense exotic beams are needed in order to study nuclei with very short half-life. To increase the release efficiency of the fission products, all the target characteristics involved must be improved (e.g. chemical composition, dimensions, physicochemical properties such as grain size, porosity, density…). In this article, we study the i...

150-250 words): 239 words The so-called CALPHAD method is widely used in metallurgy to predict phase diagrams of multi-component systems. The application of the method to oxide systems is much more recent, because of the difficulty of modelling the ionic liquid phase. Since the 1980s, several models have been proposed by various communities. Thermo...

The existence of the previously reported intermetallic phases NiW and NiW2 is refuted on the basis of new experiments involving arc-melted samples. A careful study of the literature shows that these two phases were previously evidenced only in sintered alloys and in diffusion couples, both techniques being very prone to surface contamination. It is...
