Landau theory applied to phase transitions in calcium orthotungstate and isostructural compounds
D. Errandonea
The pressure-driven tetragonal-to-monoclinic phase transition in CaWO4 and related scheelite-structured orthotungstates is analysed in terms of spontaneous strains. Based upon our…
Lattice dynamics study in PbWO4 under high pressure
F. J. Manjon, D. Errandonea, N. Garro +6
Room-temperature Raman scattering has been measured in lead tungstate up to 17 GPa. We report the pressure dependence of all the Raman modes of the tetragonal scheelite phase (PbWO…
High-pressure lattice dynamics in bulk single-crystal BaWO4
F. J. Manjon, D. Errandonea, N. Garro +6
Room-temperature Raman scattering has been measured in barium tungstate (BaWO4) up to 16 GPa. We report the pressure dependence of all the Raman-active first-order phonons of the t…
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…
