The new rare-earth fluoride borates RE2(BO3)F3 (RE=Tb, Dy, Ho) were synthesized under highpressure/ high-temperature conditions of 1:5 GPa=1200 °C for Tb2(BO3)F3 and 3:0 GPa=900 °C for Dy2(BO3)F3 and Ho2(BO3)F3 in a Walker-type multianvil apparatus from the corresponding rareearth sesquioxides, rare-earth fluorides, and boron oxide. The single-crystal structure determinations revealed that the new compounds are isotypic to the known rare-earth fluoride borate Gd2(BO3)F3. The new rare-earth fluoride borates crystallize in the monoclinic space group P21/c (Z = 8) with the lattice parameters a=16:296(3), b=6:197(2), c=8:338(2) Å , b =93:58(3)° for Tb2(BO3)F3, a= 16:225(3), b = 6:160(2), c = 8:307(2) Å , b = 93:64(3)° for Dy2(BO3)F3, and a = 16:189(3), b = 6:124(2), c = 8:282(2) Å , β= 93:69(3)° for Ho2(BO3)F3. The four crystallographically different rare-earth cations (CN=9) are surrounded by oxygen and fluoride anions. All boron atoms form isolated trigonal-planar [BO3]3- groups. The six crystallographically different fluoride anions are in a nearly planar coordination by three rare-earth cations.

CDDP was loaded onto the surface of carboxyl polymer-coated NaYF4:Yb3+/Tm3+ nanoparticles prepared by hydrothermal treatment in the form of Pt–O bonds, and delivered through cellular uptake of the NaYF4–CDDP composite.

AbstractThe rare earth fluoride borates RE4B4O11F2 (RE = Sm, Tb, Ho, Er) were synthesized in a Walker-type multianvil apparatus from the corresponding rare earth oxides and fluorides with boron oxide. Sm4B4O11F2 was obtained under high-pressure/high-temperature conditions of 6 GPa/1100°C, Tb4B4O11F2 at 7.5 GPa/1200°C, and Ho4B4O11F2 and Er4B4O11F2 at 9.5 GPa/1300°C. The single-crystal structure determinations showed that all compounds are isotypic to the known rare earth fluoride borates RE4B4O11F2 (RE = Pr, Nd, Eu, Gd, Dy). They crystallize in the monoclinic space group C2/c (Z = 4). The structure is built up from BO4 tetrahedra as well as BO3 groups connected via common corners. Here, we report about the crystallographic characterization of these new compounds in comparison to the isotypic phases RE4B4O11F2 (RE = Pr, Nd, Eu, Gd, Dy).

AbstractThis review presents a comprehensive summary of the research progress on the synthesis of rare earth fluoride nanomaterials using the most common methods of synthesis. Special focus is on syntheses utilising ionic liquids, which is a new and promising way of preparing nanomaterials without the use of dangerous organic solvents (toxic, flammable, or combustive). Rare earth fluoride nanoparticles can be obtained with a high yield, purity, and crystallinity, and with different morphologies and luminescent properties depending on the selected method of synthesis.
