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.

designed for the preparation of rare-earthoxysulfides 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-earthoxysulfide 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。
