Copper Sulfide is a crystalline solid used as a semiconductor and in photo optic applications. It is not flammable or combustible. It has a narrow range of stoichiometry ranging from Cu1.997S to Cu2.000S. Copper sulfide films of nanometer thickness are grown by atomic layer deposition (ALD) and their structural and optoelectronic properties investigated as a function of time and storage environment. However, it is not the main mineral of copper due to its scarcity. Copper sulfide nanoparticles with well-defined initial chalcocite crystal phase were subjected to oxidation followed by structural characterization. Some copper sulfides are economically important ores. This structure was initially assigned an orthorhombic cell due to the twinning of the sample crystal. Retrieved from galleries.com. (1995, November). National Center for Biotechnology Information. The preferred descriptor for such SH-containing compounds is thiol or mercaptan, i.e. Copper-sulfide minerals, such as chalcocite (Cu 2 S), bornite (Cu 5 FeS 4), and chalcopyrite (CuFeS 2) are important copper resources from copper mines (Fullston et al., 1999). As copper sulfate is a naturally occurring compound, it does not degrade under normal environmental conditions and does not reduce its presence in bodies of water by volatilization. Retrieved from azom.com. Fabrication and applications of copper sulfide (CuS) nanostructures. Copper(I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. These compounds comprise economically important minerals and synthetic materials. Preparation and properties of nanosized PdS dispersions for electrolytic plating. For example, methyl sulfide can mean CH 3 –SH. In case of contact with eyes, they should be rinsed immediately with sufficient amount of water for 15 minutes, raising the lower and upper eyelids occasionally. Copper (II) sulfide has a melting point of 220 ° C where it decomposes, is insoluble in water, hydrochloric and sulfuric acid and is soluble in nitric acid, ammonium hydroxide and potassium cyanide (Royal Society of Chemistry, 2015 ). Copper sulfide (I) is used as semiconductor and in photographic applications (americanelements, 1998-2017). Flotation tends to be used to recover and concentrate these minerals. (2014). If swallowed, call a poison control center immediately. The extent of sulfidation depends on the sulfide to CuO molar concentration ratio used. We use cookies to provide our online service. At temperatures as low as 80 °C polycrystalline thin films are synthesized, which index to the stoichiometric (Cu 2 S) chalcocite phase. Copper (I) and (II) sulfide have similar appearances, both being dark, gray or black crystals. It has the chemical compound Cu2S. They have a molecular weight of 159.16 g / mol and 95.611 g / mol and a density of 5.6 g / ml and 4.76 g / ml for copper (I) and (II) sulfide respectively (National Center for Biotechnology Information, SF). Despite extensive studies of electronic and optical properties of doped copper sulfide NC, the nonlinear optical response of Cu 2−x S NC is less explored in literature . Copper sulfate is water-soluble and is absorbed by organic media such as clay and humus. During flotation, hydrophobic minerals can be … Retrieved from onboces.org. Britannica, T. E. (2013, Aug. 23). They have a molecular weight of 159.16 g / mol and 95.611 g / mol and a density of 5.6 g / ml and 4.76 g / ml for copper (I) and (II) sulfide respectively (Nati… Electrical and spectroscopic properties of amorphous copper sulfide films treated with iodine, lithium iodide and sodium iodide. These compounds can be differentiated by their crystalline structure. Copper (I) and (II) sulphides are not classified as hazardous, however they may be toxic if swallowed due to the production of hydrogen sulphide. The DL and CuSNP were compatible with the pullulan/carrageenan biopolymer matrix.

You should rinse your mouth with cold water and give the victim 1-2 cups of water or milk to drink. Copper Sulfide Nanoparticles As a New Class of Photoacoustic Contrast Agent for Deep Tissue Imaging at 1064 nm. On the other hand, copper (II) sulfide finds applications in solar cells, superionic conductors, photodetectors, electroconductive electrodes, photothermal conversion devices, microwave protective coating, active radio wave absorbers, gas sensors and radiation polarizers Infrared (azom, 2013). Sulfide | S-2 | CID 29109 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. There is also a crystallographically-distinct phase (the mineral djurleite) with stoichiometry Cu1.96S which is non-stoichiometric (range Cu1.934S-Cu1.965S) and has a monoclinic structure with 248 copper and 128 sulfur atoms in the unit cell. Therefore, it would be interesting to investigate the NLO properties and mechanism of Cu 2−x S NC both from the viewpoint of fundamental research and for device applications. Here, CuS is studied as cathode material in lithium solid‐state batteries with an areal loading of 8.9 mg cm −2 that theoretically corresponds to 4.9 mAh cm −2 . In this Feature Article, we first introduce the optical properties of these p-type semiconductor nanostructures, particularly localized surface plasmon resonance (LSPR). These compounds can be differentiated by their crystalline structure. Retrieved from pubchem.ncbi.nlm.nih.gov.
