    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.

    作者:Kazunori Nakao、Makoto Wakeshima、Yukio Hinatsu

    日期:2019.12
    Crystal structures and magnetic properties of ternary silver sulfides AgLnS2 (Ln = Sm, Gd–Yb) were investigated. All these compounds crystallize in the monoclinic cation-ordered NaCl-type structure (space group: P21). Their magnetic susceptibilities obey the Curie-Weiss law at high temperatures. The effective magnetic moment of the rare earth ion reveals that the rare earth ions are in the trivalent

    functions as an "oxygen sponge" to remove oxygen from an oxide precursor and where the elemental chalcogen effects transformation of the oxide precursor into an oxygen-free chalcogenide reagent. The boron oxide can be separated from the reaction mixture that is left to react to form the desired chalcogenide product. Several syntheses are presented that demonstrate the broad functionality of the technique
    锕系硫属化物对位于软配体配位环境中的锕系元素中 5f 电子行为的基础研究很重要。由于锕系元素对氧表现出极高的亲和力,因此合成不含氧化物杂质的相纯锕系元素硫属化物材料是一项巨大的挑战,而且需要无氧起始材料的可用性和使用。在此,我们报告了一种新方法,即硼 - 硫属元素混合物 (BCM) 法,该方法基于使用硼 - 硫属元素混合物合成相纯铀硫属元素化物,其中硼充当“氧气海绵”以去除氧气来自氧化物前体并且其中元素硫族元素影响氧化物前体向无氧硫族化物试剂的转变。氧化硼可以从反应混合物中分离出来,反应混合物使其反应形成所需的硫属化物产物。介绍了几种合成方法,展示了该技术的广泛功能,并讨论了显示潜在驱动力的热力学计算。具体而言,制备了三类硫属化物,包括新的(稀土硫化铀和碱金属硫代磷酸钍)和先前报道的化合物以验证该方法:二元铀和硫化钍、固态反应中的氧化物到硫化物转化,以及助焊剂晶体生长反应中锕系硫属化物的原

    by diffuse reflectance spectroscopy on a complete suite of rare earth sesquisulfide compounds of varying structure type. Optical band gaps were extracted from these data. The observed band gaps tend to vary with crystal structure type but many compounds with the same structure have similar band gaps independently of the particular rare earth ion. The ordered α-structure has a substantially lower band
    摘要 已经通过漫反射光谱对一整套不同结构类型的稀土倍半硫化物化合物测量了光吸收边光谱。从这些数据中提取光学带隙。观察到的带隙往往随晶体结构类型而变化,但许多具有相同结构的化合物具有相似的带隙,独立于特定的稀土离子。对于除 La 2 S 3 之外的所有化合物,有序 α 结构的带隙明显低于缺陷 γ 结构。
  • Trends in thermodynamic parameters of phase transitions of lanthanide sulfides SrLnCuS3 (Ln = La–Lu)
    作者:Anna V. Ruseikina、Oleg V. Andreev、Eugenia O. Galenko、Semyon I. Koltsov

    SrLnCuS3 (Ln = La–Lu) compounds melt incongruently. Their thermochemical parameters are determined. The melting temperatures and the enthalpies of melting are: for SrLaCuS3, T = 1513 K and ΔH = 6.9 kJ mol−1; for SrCeCuS3, T = 1468 K and ΔH = 5.2 kJ mol−1; for SrPrCuS3, T = 1459 K and ΔH = 13.2 kJ mol−1; for SrNdCuS3, T = 1429 K and ΔH = 16.8 kJ mol−1; and for SrSmCuS3, T = 1605 K and ΔH = 2.8 kJ mol−1. Three high-temperature polymorphic transitions are found to occur in SrLnCuS3 (Ln = Sm, Gd–Lu) compounds. The parameters of these transitions are determined: for SrSmCuS3, Tα ↔ β = 1452 K, ΔHα ↔ β = 3.0 kJ mol−1, Tβ ↔ γ = 1464 K, ΔHβ ↔ γ = 0.2 kJ mol−1, Tγ ↔ δ = 1476 K, and ΔHγ ↔ δ = 1.1 kJ mol−1; for SrDyCuS3, Tα ↔ β = 1530 К, Tβ ↔ γ = 1568 К, and Tγ ↔ δ = 1585 K; for SrTmCuS3, Tα ↔ β = 1580 K, Tβ ↔ γ = 1618 K, and Tγ ↔ δ = 1631 K; and for SrYbCuS3, Tα ↔ β = 1567 K, Tβ ↔ γ = 1608 K, and Tγ ↔ δ = 1621 K. The transitions are observed both upon heating and upon cooling. The high-temperature phases are not quenchable. Phase-transition temperature versus r(Ln3+) curves for SrLnCuS3 (Ln = La–Lu) feature the tetrad effect. The SrLnCuS3 (Ln = La–Nd) compounds are classified as thiocuprates; their melting temperatures decrease systematically from La to Nd. The SrCuLnS3 (Ln = Sm, Gd–Lu) compounds are classified as thiolanthanates; their melting temperatures increase in the order from Sm to Tm and from Tm to Lu.
    SrLnCuS3 (Ln = La–Lu) 化合物不一致熔化。测定它们的热化学参数。熔化温度和熔化热函为: 对于 SrLaCuS3,T = 1513 K 且 ΔH = 6.9 kJ mol−1;对于 SrCeCuS3,T = 1468 K 且 ΔH = 5.2 kJ mol−1;对于 SrPrCuS3,T = 1459 K 且 ΔH = 13.2 kJ mol−1;对于 SrNdCuS3,T = 1429 K 且 ΔH = 16.8 kJ mol−1;对于 SrSmCuS3,T = 1605 K 且 ΔH = 2.8 kJ mol−1。在 SrLnCuS3 (Ln = Sm、Gd–Lu) 化合物中发现了三种高温多晶型转变。确定这些转变的参数:对于 SrSmCuS3,Tα ↔ β = 1452 K,ΔHα ↔ β = 3.0 kJ mol−1,Tβ ↔ γ = 1464 K,ΔHβ ↔ γ = 0.2 kJ mol−1,Tγ ↔ δ = 1476 K,且 ΔHγ↔δ=1.1kJmol−1;对于 SrDyCuS3,Tα ↔ β = 1530 К,Tβ ↔ γ = 1568 К,Tγ ↔ δ = 1585 K;对于 SrTmCuS3,Tα↔β=1580K,Tβ↔γ=1618K,Tγ↔δ=1631K;对于 SrYbCuS3,Tα ↔ β = 1567 K,Tβ ↔ γ = 1608 K,Tγ ↔ δ = 1621 K。在加热和冷却时都可以观察到转变。高温相不可淬火。 SrLnCuS3 (Ln = La–Lu) 的相变温度与 r(Ln3+) 曲线具有四分体效应。 SrLnCuS3 (Ln = La-Nd) 化合物被归类为硫代铜酸盐;它们的熔化温度从 La 到 Nd 系统地降低。 SrCuLnS3 (Ln = Sm, Gd–Lu) 化合物被归类为硫代镧酸盐;它们的熔化温度按从Sm到Tm、从Tm到Lu的顺序增加。

    influence of the lanthanide size on the structures and properties of thiophosphates, a thiophosphate series containing different lanthanides was synthesized via high temperature flux crystal growth and their structures and physical properties analyzed and compared. Layered thiohypophosphates NaLnP2S6 (Ln = La, Ce, Pr) and thiopyrophosphates CsLnP2S7 (Ln = Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Yb, Y) were grown
    为了确定镧系元素尺寸对硫代磷酸盐的结构和性能的影响,通过高温助熔剂晶体生长合成了含有不同镧系元素的硫代磷酸盐系列,并对其结构和物理性能进行了分析和比较。层状硫代次磷酸盐NaLnP 2 S 6(Ln = La,Ce,Pr)和硫代焦磷酸盐CsLnP 2 S 7(Ln = Pr,Nd,Sm,Gd,Tb,Dy,Ho,Er,Yb,Y)在两个系列中使用一致的反应条件从碘化物助熔剂中生长出来。在适度还原的碘化物通量反应条件下,观察到磷从+5还原到+4氧化态的罕见例子。两种最终的结构类型均基于镧系元素硫代磷酸酯片材,且碱金属阳离子位于它们之间。进行了磁化率测量,并揭示了样品的居里-魏斯行为,CsSmP 2 S 7样品中有Van Vleck贡献。紫外可见数据与文献资料非常吻合,表明硫化物环境对局域4f轨道的影响很小。
