We report optical absorption and luminescence measurements in pure and trivalent neodymium (Nd3+) doped LaVO4 crystals up to 25 GPa. Nd3+ luminescence has been employed as a tool to follow the structural changes in the crystal. We also present band-s

In this work we study the local structure of layered G a 1 − x I n x S e alloys by means of X-ray Absorption. We complement our research with a Raman study. The available alloys have compositions close to the host binaries. The dependence of XANES

A structural transformation from the zircon-type structure to an amorphous phase has been found in YVO4:Eu3+ nanoboxes at high pressures above 12.7 GPa by means of x-ray diffraction measurements. However, the pair distribution function of the high-pr

Recent experimental measurements and ab initio calculations in scheelite CaWO 4 , SrWO 4 , BaWO 4 , PbWO 4 , EuWO 4 and YLiF4 crystals reveal the existence of complex high-pressure phase diagrams, which present striking differences but also relevant

The structural properties of CaWO{sub 4}, SrWO{sub 4}, BaWO{sub 4}, PbWO{sub 4}, and EuWO{sub 4} scintillating crystals under pressure have been studied by X-ray powder diffraction, X-ray absorption near-edge structure measurements, Raman spectroscop

In this paper we investigate the electronic structure of Zn 1-x Co x O by means of optical absorption measurements under pressure. Thin films of Zn 1-x Co x O with different Co content (from 1 to 30%) were prepared by pulsed laser deposition on mica

In this paper, we combine a theoretical study of the structural phases of CaWO 4 and SrWO 4 under high pressure along with the results of angle-dispersive X-ray diffraction (ADXRD) and X-ray absorption near-edge structure (XANES) measurements of both

We report energy dispersive x-ray diffraction experiments carried out in the Te rich side of ZnSexTe1-x alloys with the aim of characterizing the cinnabar phase. In the samples studied (x =0.55, 0.2, 0.1 and 0.0) the cinnabar phase is observed both i
