In this article the doping of chromium in a lead metasilicate glass is explored using Raman, UV–Vis, and Cr K-edge XANES spectroscopy. Our results indicate that the Cr ions are predominantly present as CrO42− complexes, with a minor amounts of Cr

Eu-doped (Y2.99-xGdx)Al5O12 phosphors (with x = 0, 0.5, 1, 1.5, 2, 2.5, and 2.99) were prepared by a sol-gel method using polyvinylalcohol (PVA) as gel agent. The crystal structures were characterized through X-ray diffraction and the resulting data

In this paper we report about the in-situ experiments on cobalt titanate (CoTiO3), in which were investigated the compressibility at high pressures up to 24.6 GPa, at room temperature, using synchrotron X-ray diffraction (SXRD) and also the thermal e

It is known that barium disilicate (BS2) glass exhibits two prominent exothermic peaks between the glass transition and melting temperatures in calorimetric experiments, however, their cause is not known. In this work, glass-ceramic samples were prod

Raman scattering and XRD data allied to Rietveld refinement were used to investigate the structural and vibrational properties of Pb1-xCoxTiO3 samples with x ranging from 0.0 to 1.0. The results showed reductions in the tetragonallity factor and in t
