The thiophosphates of the rare earths REPS 4(RE=Y, La~Lu) were prepared by solid state reaction. Their unit cell parameters and the structures of HoPS 4, ErPS 4 and TmPS 4 were determined by X ray powder diffra...
The Raman spectroscopy study of LnPS 4 series compounds with tetragonal xenotime structure shows that the symmetrical stretching vibration frequency ν 1 increases linearly with the lanthanide contraction, i.e.,...
