Abstract:

Solid-state absorption and Raman phonon spectroscopic investigations of PrCl3, PrBr3, and NdBr3 under high pressure have been carried out at room temperature. These studies showed that the UCl3-type hexagonal form of PrCl3 and PrBr3 converts with the application of pressure to the PuBr3-type orthorhombic crystal structure. The absorption and Raman spectra obtained from PrBr3 and NdBr3 at pressures above ~260 kbar exhibit differences from spectra obtained at lower pressures, where they exhibit the PuBr3-type orthorhombic structure. These spectral differences suggest that a phase transformation might have taken place to an as-yet-unidentified crystal structure.
