  • Polarized Raman spectroscopy has been used to obtain the room-temperature phonon spectra of the series of rare earth orthovanadate single crystals: SmVO4, HoVO4, YbVO4 and LuVO4. The observed Raman frequencies follow the overall mode distribution expected for RVO4 compounds with the tetragonal zircon structure. The variation of the mode frequency with atomic number across the lanthanide orthovanadate series was investigated, and the trend exhibited by the internal modes was explained by considering the force constants of VO4 tetrahedron.
  • The spectroscopic properties of orthovanadates M/sup 2/M/sup 4 +/(VO/sub 4/)/sub 2/-r.e. were investigated. The levels for Eu/sup 3 +/, Nd/sup 3 +/, and Pr/sup 3 +/ ions and the Stark splitting and relative line intensities of the luminescence of the Eu/sup 3 +/ ion in CaZr(VO/sub 4/)/sub 2/ are reported.
