Description
The trifluorides of La and Gd crystallize in different structures: LaF3 is of the hexagonal tysonite (P bar 31c) type, while GdF3 crystallizes in orthorhombic (Pnma) symmetry. Solid solutions of the type La1-xGdxF3 exist in the hexagonal structure to x = 0.5 and convert to the orthorhombic phase at x = 0.75. In this paper, lattice parameters are reported and the x-ray excited luminescence of Gd3+ in these compounds is discussed with particular emphasis on the Gd3+ site symmetry difference C2 in LaF3 and Cs in GdF3
