Chalcogenide Perovskites for Photovoltaics
Nano Letters, 2015Chalcogenide perovskites are proposed for photovoltaic applications. The predicted band gaps of CaTiS3, BaZrS3, CaZrSe3, and CaHfSe3 with the distorted perovskite structure are within the optimal range for making single-junction solar cells. The predicted optical absorption properties of these materials are superior compared with other high-efficiency ...

The magnetism of the uranium chalcogenides
Journal of Magnetism and Magnetic Materials, 1987Abstract A localized model has been developed for the ferromagnetic uranium chalcogenides that describes their static and dynamic magnetic properties. The model describes the Curie-Weiss temperature, the effective paramagnetic moment, the ordered moment, the low temperature structural distortion and the temperature dependence of the C 44 elastic ...

The chalcogenide glass Tl(2)SeAs(2) Te(3) has been evaluated as a thermistor bolometer material for room temperature operation. Thin film bolometers were fabricated on mica, glass, and sapphire substrates by both hot-pressing and rf sputtering techniques. Best results were achieved with 10-micro thick Tl(2)SeAs(2) Te(3) elements on thin mica substrates.

This chapter gives an account of the newer developments on the synthesis and reactivity of phosphine chalcogenides, mainly oxides and sulfides. A series of new synthetic methods for phosphine oxides is discussed, followed by preparations utilizing simple P-reagents such as P(iii)- and P(v)-chlorides, and >P(O)H species.

The use of phosphine chalcogenides in the preparation of cobalt chalcogenides
Journal of Organometallic Chemistry, 1993Abstract Dicobalt octacarbonyl reacts with TeP n Bu 3 , SeP n Bu 3 or SP n Bu 3 to give solid state cobalt telluride, cobalt selenide and cobalt sulfide, respectively. In each case a cluster compound of the form Co 6 E 8 (P n Bu 3 ) 6 can be isolated from the reaction of the phosphine chalcogenide with cobalt carbonyl, and subsequently carried on

CHALCOGENIDE CENTERED GOLD COMPLEXES
Comments on Inorganic Chemistry, 2006Chalcogenide-centred gold complexes are an important class of compounds in which a central chalcogen is surrounded by several gold atoms or gold and other metals. They have special characteristics such as unusual geometries, electron deficiency and properties such as luminescence or non-linear optical properties.

Chalcogenide clusters of copper and silver from silylated chalcogenide sources
Chem. Soc. Rev., 2013This review summarizes the rich structural variety of copper and silver chalcogenide clusters with protecting ligand shells of phosphane and/or organic ligands that were generated starting out from silylated chalcogenide sources. This route turned out to be fairly selective and thus allows for the isolation of uniform, polynuclear to nanosized cluster ...

Chalcogenide Superconductors -- A Search.
1994Abstract : Experimental and theoretical evidence and arguments are presented to justify a search for new superconductors, similar to the perovskite- based high temperature superconductors, but with the oxygen replaced by a chalcogen, that is sulfur, selenium or tellurium.

Chalcogenide coatings of Ge_15Sb_20S_65 and Te_20As_30Se_50
Applied Optics, 2007Chalcogenide coatings are investigated to obtain either optical components for spectral applications or optochemical sensors in the mid-infrared. The deposition of Ge(15)Sb(20)S(65) and Te(20)As(30)Se(50) chalcogenide glasses is performed by two physical techniques: electron-beam and pulsed-laser deposition.
