Raman Scattering Spectra of TmPO4.
Abstract
Raman Scattering spectra of TmPO(4) have been studied between 5 K and room temperature. We have observed four electronic transitions between the crystal field split levels of the Tm(3+) ion (3H6) which is at the D(2d) site symmetry of the lattice. In addition to electronic transitions, we have observed eleven phonon peaks which we assign to the internal and external vibrations of the PO4(3-) ion in the irreducible representation of D(4h). Like several other rare earth phosphates and vanadates, no phase transition has been observed in this crystal. (Author)
