Raman investigations of rare earth orthovanadates
Polarized Raman spectroscopy has been used to obtain the room-temperature phonon
spectra of the series of rare earth orthovanadate single crystals: Sm VO 4, Ho VO 4, Yb
VO 4, and Lu VO 4. The observed Raman frequencies follow the overall mode
distribution expected for REVO 4 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 …
