  Thermolysis of lanthanide dithiocarbamate complexes

  摘要：

  Polycrystalline lanthanide sulfide materials were formed at low temperatures using a single-source precursor based on the lanthanide dithiocarbamate complex. The synthesis temperatures aye generally lower than standard solid state preparations, avoid toxic sulfurizing gases and provide a convenient route to prepare lanthanide chalcogenide nanoparticles. Depending on the reaction conditions and oxophilicity of the lanthanide, the Sulfide material was formed with oxidized products including oxysulfides, oxysulfates and the oxide.

  Luminescence of Ln(III) Dithiocarbamate Complexes (Ln = La, Pr, Sm, Eu, Gd, Tb, Dy)

  摘要：

  We have discovered room temperature photoluminescence in SM3+ and Pr3+ dithiocarbamate complexes. Surprisingly, these complexes exhibit more intense emission than those of the Eu3+, Tb3+, and Dy3+ analogues. The electronic absorption, excitation, and emission spectra are reported for the complexes [Ln(S2CNR2)(3)L] and NH2Et2[Ln(S2CNEt2)(4)], where Ln = Sm, Pr; R = ethyl, butyl, benzyl; and L = 1,10-phenanthroline, 2,2'-bipyridine, and 5-chloro-1,10-phenanthroline. The lowest ligand-localized triplet energy level (T-1) of the complexes are determined from the phosphorescence spectra of analogous La3+ and Gd3+ chelates. The luminescence decay curves were measured to determine the excited-state lifetimes for the Pr3+ and Sm3+ complexes. X-ray crystal structures of Sm((S2CNBu2)-Bu-i)(3)phen, Pr(S2CNEt2)(3)phen, and Pr((S2CNBu2)-Bu-i)(3)phen are also reported.

• A new continuous two-step molecular precursor route to rare-earth oxysulfides Ln2O2S

  designed for the preparation of rare-earth oxysulfides Ln2O2S (Ln=Y, La, Pr, Nd, Sm–Lu). This new route involves a first oxidation step leading to the rare-earth oxysulfate Ln2O2SO4 which is subsequently reduced to the rare-earth oxysulfide Ln2O2S by switching to a H2–Ar atmosphere. The whole process occurs at a temperature significantly lower than usual solid state synthesis (T≤650 °C) and avoids the use

  设计了一个连续的两步式分子前体途径，用于制备稀土氧硫化物Ln 2 O 2 S（Ln = Y，La，Pr，Nd，Sm-Lu）。该新路线涉及第一步氧化步骤，该氧化步骤导致了稀土氧硫酸盐Ln 2 O 2 SO 4，随后通过切换至H 2 -Ar气氛而还原为稀土氧硫化物Ln 2 O 2 S。整个过程的温度大大低于通常的固态合成（T≤650°C），避免使用危险的硫基气体，为合成整个Ln 2 O 2 S系列提供了便捷的途径。分子前体由杂二硫代氨基甲酸酯复合物组成[ Ln（Et 2 dtc）3（phen）]和[ Ln（Et 2 dtc）3（bipy）]（Et 2 dtc = N，N-二乙基二硫代氨基甲酸酯; phen = 1,10-菲咯啉; bipy = 2,2'-联吡啶）并通过a新的高产高纯度合成路线。分子前体的性质决定了最低合成温度，因此影响了最终Ln 2 O的纯度2 S结晶相。
