  水分散性无配体的稀土氟化物纳米粒子：水转移与NaREF4-to-REF3相变。

  摘要：

  含油酸酯封端的10 nm以下α-和β-NaREF4NPs的化学稳定性（RE = Y，Pr，Nd，Sm，Eu，Gd，Tb，Dy，Ho，Er，Yb，Lu对于α-和RE = β-相NPs的Pr，Nd，Sm，Eu，Gd，Tb，Dy在酸性条件下进行评估，该酸性条件用于去除配体以实现水分散性。已经发现，对于如此小的NP，为了使水转移有效并且产生良好分散的无配体的NP，pH必须低于3。与通常认为的NaREF4的良好化学稳定性形成鲜明对比的是，观察到这些条件可能会导致NaREF4 NP相转变为更大的六方或正交相REF3的风险，具体取决于NP的组成。发现α/β-NaREF4和六方/斜方REF3相的热力学稳定性（由RE离子选择决定）与NPs的化学稳定性之间存在相关性。例如，β-NaGdF4NPs保持稳定，而α-NaGdF4NPs相转变成六方GdF3。更一般而言，基于较轻RE离子的NaREF4 NP更倾向于相变，而基于较重RE离子的NaREF4

  We report a general synthesis of high-quality cubic (alpha-phase) and hexagonal (beta-phase) NaREF4 (RE: Pr to Lu, Y) nanocrystals (nanopolyhedra, nanorods, nanoplates, and nanospheres) and NaYF(4):Yb,Er/Tm nanocrystals (nanopolyhedra and nanoplates) via the co-thermolysis of Na(CF3COO) and RE(CF3COO)3 in oleic acid/oleylamine/1-octadecene. By tuning the ratio of Na/RE, solvent composition, reaction

• Highly Luminescent, Visible-Emitting Lanthanide Macrocyclic Chelates Stable in Water and Derived from the Cyclen Framework

  Two new tetraazamacrocyclic ligands are designed with the aim of sensitizing the luminescence of Tb(Ill) and Eu(Ill) ions in water: L51,4,7,10-tetrakis[N-(phenacyl)carbamoylmethyl]-1,4,7,10-tetraazacyclododecane} and L6 1,4,7,10-tetrakis[N-(4-phenylphenacyl)carbamoylmethyl]-1,4,7,10-tetraazacyclododecane}. These ligands react with lanthanide trifluoromethanesulfonates to yield stable 1:1 complexes in water (log K = 12.89 +/- 0.15 for EuL5). X-ray diffraction on [Tb(L5)(H2O)](CF3SO3)(3) (P (1) over bar, a = 13,308(3) Angstrom, b = 14.338(3) Angstrom, c = 16.130(3) Angstrom, alpha = 101.37(3)degrees, beta = 96.16(3)degrees, gamma = 98.60(3)degrees) shows the Tb(III) ion lying on a C-4 axis and being 9-coordinate, with one water molecule bound in its inner coordination sphere. The absolute quantum yields are determined in aerated water for the complexes formed with ions used in fluoroimmunoassays (Ln = Sm, Eu, To, and Dy). Large values are found for [Tb(H2O)(L5)](3+) and [Eu(H2O)(L6)](3+), in line with the molecular design of the receptors: 23.1% and 24.7%, respectively. The intense luminescence of these ions results from efficient intersystem crossing and L Ln energy transfer processes, as well as from a suitable shielding of the emitting ions from radiationless deactivation.

• Ytterbium – Doped Prussian blue: Fabrication, photothermal performance and antibacterial activity

  The application of photothermal therapy (PTT) to defeat bacterial infections has attracted great attention in the past years. Prussian blue (PB) is a potential photothermal agent in bacteria obliteration. The electron density of cyanide bonds (-C N-) in PB plays a decisive role on its PTT performance. Meanwhile, recent reports indicated that encapsulating PB shell on lanthanide nanomaterials core could effectively enhance its photothermal efficiency. Hence, a series of lanthanide ions, including erbium (Er3+), dysprosium (Dy3+), thulium (Tm3+), ytterbium (Yb3+), doped PB nanocubes were fabricated by a simple doping method due to the differences between lanthanide and iron on changing electron density of cyanide bond. And the Yb3+ doped PB (PB-Yb) has the best PTT performance of all nanocubes. Structure analyzing results indicate that 9% Fe (Fe2+ or Fe3+) were replaced by Yb3+ in PB-Yb, which could raise its electron density to improve its PTT performance. And the antibacterial test also verified the conclusion. All above results proved that doping proper lanthanide ions into PB is a simple and effective way to improve its photothermal performance.
