  摘要：

  Samarium dithiocarbamate complexes dtc(3)Sm and their adducts dtc(3)SmL were prepared, studied, and used as precursors for deposition of SmS films. The influence of the composition and structure of the complexes on the properties of the SmS films was examined.

  Abstract Reflection spectra have been measured on semiconducting SmS, SmSe and SmTe single crystals at 2 K in the photon energy region of 3 ∼ 6 eV. From a comparison of the spectra in these Sm monochalcogenides with those in BaS and BaSe, the reflection peaks observed in this photon energy region are identified as the Wannier excitons associated with the band-edges at the X -point and the Γ-point.

  摘要 已经在 3 ∼ 6 eV 的光子能量范围内在 2 K 下测量了半导体 SmS、SmSe 和 SmTe 单晶的反射光谱。通过将这些 Sm 单硫属元素化物中的光谱与 BaS 和 BaSe 中的光谱进行比较，在该光子能量区域中观察到的反射峰被识别为与 X 点和 Γ 点的带边相关的万尼尔激子。SmSe 的反射峰和电反射光谱的温度依赖性支持这种识别。在观察到的激子光谱的基础上讨论了半导体 Sm 单硫属元素化物的能带结构。

  Electrical and magnetic properties of mixed-valence rare-earth sulfides, (Sm1−xGdx)3S4, were investigated. The valence transition from trivalent to divalent samarium ions takes place gradually with increasing gadolinium concentration. In the range between x=0.80 and x=0.85, a drastic change from semiconducting to metallic conduction was observed. This phenomenon is explained by the valence change of

  研究了混合价稀土硫化物 (Sm1-xGdx)3S4 的电学和磁学性质。随着钆浓度的增加，从三价钐离子到二价钐离子的价态转变逐渐发生。在 x=0.80 和 x=0.85 之间的范围内，观察到从半导体传导到金属传导的剧烈变化。这种现象可以用固溶体中钐离子的价态变化来解释。半导体硫化物中的传导机制是Sm2+和Sm3+位点之间的电子跳跃，金属硫化物中的传导机制是通过传导电子的带传导。金属样品的电阻率与温度曲线的最大值出现在其居里温度附近。发现这种行为是由磁极化子的形成引起的。

  Metallic SmS thin films with 100–2000 nm in thickness were prepared by rf magnetron sputtering. The metallic- to semiconductor-phase transition was induced by a regeneratively amplified mode-locked Ti:sapphire laser. The shifts of the (200) peak due to the phase transition were observed by grazing incidence x-ray diffraction (GIXD) analysis. This phase transition was accompanied by the significant

  通过射频磁控溅射制备厚度为 100-2000 nm 的金属 SmS 薄膜。金属到半导体的相变是由再生放大锁模钛蓝宝石激光器引起的。通过掠入射 X 射线衍射 (GIXD) 分析观察到由于相变引起的 (200) 峰的位移。这种相变伴随着薄膜在近红外区域高达 45% 的显着反射率变化。根据 GIXD 的深度分布，从飞秒激光脉冲照射的薄膜表面算起相变层的深度约为 200 nm。

  (1–3 nm)—ranging from lanthanum as one of the largest (187 pm) to scandium as the smallest (161 pm) rare-earth metal—is shown. Size, oxidation state, and reactivity of the nanoparticles are examined (e.g., electron microscopy, electron spectroscopy, X-ray absorption spectroscopy, selected reactions). Whereas the nanoparticles are highly reactive (e.g. in contact to air and water), they are chemically stable as THF
