Preparation of transition metal chalcogenide fluorides
Journal of Fluorine Chemistry, 1982Abstract The species WSF4 has been observed in solution by reacting WSCl4 with HF or XeF2 in dry CH3CN, and was initially isolated as a solid by reacting WF6 with Sb2S3 at 300°C. In this paper new methods for preparing WSF4 by thermal or room temperature reactions are outlined.

Cluster Transition Metal Chalcogenide Halides
Russian Chemical Reviews, 1985The literature data on cluster transition metal chalcogenide halides are described systematically and discussed. The structures of these compounds are examined and compared with those of the analogous cluster metal halides and chalcogenides. The principal preparative methods of synthesis of the cluster chalcogenide halides are discussed and a ...

Transition-metal-doped chalcogenide lasers
Journal of Electronic Materials, 2002Broadly tunable mid-infrared lasers are desirable for a number of scientific, remote-sensing, and military applications. Recently, Cr2+-doped chalcogenide lasers have emerged as an attractive source of tunable laser radiation in the 2-3.4-µm region. This paper provides a brief introduction to this field, summarizes key laser work to date, and provides ...

Ternary Transition Metal Chalcogenides AB2X4
1993Ternary chalcogenides of the type AB2X4 (A, B = transition metals and X = S, Se, Te) generally adopt either the cubic spinel structure or defect structures related to NiAs. It will be shown that both the metal ions and the polarizability of the anion determine which of these structures is favored. In the cubic close-packed anion array of the thiospinel

Photoinduced Structural Conversions of Transition Metal Chalcogenide Materials
The Journal of Physical Chemistry A, 2010The conversions of NiAs-type structures of transition metal chalcogenides (FeS and CoSe) to pyrite-type structures of dichalcogenides (FeS(2) and CoSe(2), respectively) under irradiation by HeNe laser (wavelength, 632.8 nm; intensity, 6 x 10(4) W/cm(2)) have been investigated using Raman spectroscopy.

Microscopic studies of transition metal chalcogenides
Journal of Crystal Growth, 1976The reaction of single crystals of transition metal dichalcogenides (MX2 layer structures) with n-butyllithium to form LiMX2 have been followed with the optical microscope. Small crystals are observed to intercalate Li with movement of a distinct front through the crystal. Larger crystals crack but remain intact.
