摘要： Metal sulfides are prepared by reacting a compound of the metal and an oxygen-containing anion, with a source of carbonyl sulfide. The resulting metal sulfide is not contaminated by hydrogen, as in the form of hydroxides, and is suitable for use in photoluminescence and electroluminescence applications. The starting material is preferably a metal oxalate, which may be appropriately doped, and the source of the carbonyl sulfide is preferably a mixture of carbon monoxide and sulfur dioxide (to produce a reducing mode) or a mixture of carbon dioxide and carbon disulfide (to produce an oxidizing mode). Oxyanions that decompose to a produce a nascent oxygen anion, as does the oxalate, are preferred, as they can be reacted to achieve a high conversion rate to the sulfide.

摘要： Novel single layer materials of the form MX.sub.2, where MX.sub.2 is a layer-type dichalcogenide such as MoS.sub.2, TaS.sub.2, WS.sub.2, or the like, exfoliated by intercalation of an alkali metal, and immersion in water, are disclosed. MoS.sub.2 has been exfoliated into monolayers by intercalation with lithium followed by reaction with water. X-ray diffraction analysis demonstrates that the exfoliated MoS.sub.2 in suspension is in the form of one-molecule-thick sheets. X-ray patterns from dried and re-stacked films of exfoliated MoS.sub.2 indicate that the layers are randomly stacked. By adsorbing monolayers or precipitating clusters of various species such as compounds of Co, Ni, Pb, Cd, Al, Ce, In and Zn, on MoS.sub.2 while the sulfide is suspended as single layers and then recrystallizing, a new group of inclusion compounds can be formed. In the re-crystallized or re-stacked materials, the inter-layer spacing can be expanded or contracted compared to MoS.sub.2.

摘要： In order to obtain substances that are optically transparent in the infrared range, usable in the manufacture of optical fibers or radiation emitters, a metal or metalloid chalcogenide other than an oxide is produced by a double-substitution reaction between a starting chalcogen compound--particularly a hydride such as H.sub.2 S, H.sub.2 Se or H.sub.2 Te--and a salt of the desired metal or metalloid, e.g. a chloride. The starting compound and the reactant salt preferably are vaporized at a temperature below the melting point of the resulting metal chalcogenide which thereupon precipitates in the reaction chamber.

摘要： A low cost chemical spray deposition of metal and mixed metal chalcogenides is accomplished by spray depositing an oxide film from a mixture of a salt of the metal in solution with a water soluble hydrocarbon and water solvent. This oxide film is subjected to a heat treatment in the presence of a chalcogenide gas to induce an ion exchange process transforming the metal oxide or mixed metal oxide into the chalcogenide films of the present invention.The deposition process is used to provide efficient selective absorbing surfaces for a solar thermal energy converter. The process may further be employed to produce a thin film photovoltaic device for converting light energy into electricity.

摘要： Thiosulphate ions present in gas purification liquors, particularly those employed for removing H.sub.2 S by washing with aqueous alkaline solutions of vanadium compounds and anthraquinone disulphonic acids, are decomposed to sulphide and hydroxyl ions by exposing the liquor to a hydrogen rich gas at elevated temperature e.g., 650.degree. C. The liquor may be evaporated and the solid residue subjected to decomposition. Any thiocyanate ions are hydrolyzed; it being necessary to mix steam with the hydrogen rich gas if a solid residue is being decomposed.
