Abstract
Hexagonal LaF<sub>3</sub>:Yb<sup>3+</sup>/Ln<sup>3+</sup> and tetragonal LaOF:Yb<sup>3+</sup>/Ln<sup>3+</sup> have been successfully prepared <italic>via</italic> a two-step reaction, which includes a facile aqueous ligand free solution method and the following heat treatment of the as-prepared LaF<sub>3</sub> precursor.
