Solid Solutions of Rare Earth Cations in Mesoporous Anatase Beads and Their Performances in Dye-Sensitized Solar Cells.

Solid solutions of the rare earth (RE) cations Pr(3+), Nd(3+), Sm(3+), Gd(3+), Er(3+) and Yb(3+) in anatase TiO2 have been synthesized as mesoporous beads in the concentration range 0.1-0.3% of metal atoms.
