Optical absorption of divalent metal tungstates: Correlation between the band-gap energy and the cation ionic radius
R. Lacomba-Perales, J. Ruiz-Fuertes, D. Errandonea +2
We have carried out optical-absorption and reflectance measurements at room temperature in single crystals of AWO4 tungstates (A = Ba, Ca, Cd, Cu, Pb, Sr, and Zn). From the experim…
Effects of high pressure on the optical absorption spectrum of scintillating PbWO4 crystals
D. Errandonea, D. Martinez-Garcia, R. Lacomba-Perales +2
The pressure behavior of the absorption edge of PbWO4 was studied up to 15.3 GPa. It red-shifts at -71 meV/GPa below 6.1 GPa, but at 6.3 GPa the band-gap collapses from 3.5 eV to 2…
Determination of the high-pressure crystal structure of BaWO4 and PbWO4
D. Errandonea, J. Pellicer-Porres, F. J. Manjon +10
We report the results of both angle-dispersive x-ray diffraction and x-ray absorption near-edge structure studies in BaWO4 and PbWO4 at pressures of up to 56 GPa and 24 GPa, respec…
High-pressure structural study of the scheelite tungstates CaWO4 and SrWO4
D. Errandonea, J. Pellicer-Porres, F. J. Manjon +10
Angle-dispersive x-ray diffraction (ADXRD) and x-ray absorption near edge structure (XANES) measurements have been performed in the AWO4 tungstates CaWO4 and SrWO4 under high press…
