single crystalX-raystructures, are advantageous in terms of being anhydrous and having lower decomposition temperatures in comparison to the homometallic precursor Y(TFA)3(H2O)3. In addition, they also contain chelating glyme ligands, which act as capping reagents during decomposition to control the NaYF4 particle size and render them monodisperse in organic solvents.
