Ioffe Institute in Russia. lead(IV) sulfate is a product. Its detection mechanism is based on a change of conductivity of a polycrystalline thin-film of the active material when photons are incident. [7] Several groups have since reported thermoelectric figures of merit exceeding unity, which is the characteristic of a high performance thermoelectric.[8][9][10]. The second system, called the common system, is not conventional but is still prevalent and used in the health sciences.This system recognizes that many metals have two common cations. [14] It is based on the deposition of the active material by thermal evaporation, followed by specific thermal treatments. lead(IV) sulfide: PbS 2: zinc selenide* ZnSe: gallium(I) iodide: GaI: vanadium(III) chloride: VCl 3: nickel(III) selenide: Ni 2 Se 3: iron(III) bromide: FeBr 3: silver sulfide* Ag 2 S: tin(IV) chloride: SnCl 4: manganese(II) fluoride: MnF 2: antimony(V) bromide: SbBr5: cobalt(III) oxide: Co 2 O 3: titanium(IV) oxide: TiO 2 It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. The (IV) tells us that Lead has a charge of +4. InChI=1S/Pb/q+4 It does not require cooling, but performs better at lower temperatures. Ionic Compound Formula K sp. Provided below is a list of the chemical formulas of some common chemical compounds (along with their molecular weights). 5. This new processing method has been recently developed in Spain. Formula: Early research works on the material as infrared detector were carried out during the 1930s and the first useful devices were processed by Germans, Americans and British during and just after World War II. The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. For Lead (IV) sulfate we have a transition metal and a polyatomic ion. (Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.)

Plumbic Selenide. These photons are absorbed inside the PbSe micro-crystals causing then the promotion of electrons from the valence band to the conduction band. PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. Use the Common Ion Table to find the formula and charge for the sulfate ion. Lead selenide is a photoconductor material. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. It is a grey crystalline solid material. Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it. Search results for lead powder at Sigma-Aldrich. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. Chemical bath disposition (CBD) is the standard manufacturing method. Because of technological limitations associated to this method of processing, nowadays the biggest CBD PbSe detector format commercialized is a linear array of 1x256 elements. [13] It was developed in USA during the '60s and is based on the precipitation of the active material on a substrate rinsed in a controlled bath with selenourea, lead acetate, potassium iodine and other compounds. [11], As a sensitive material to the infrared radiation, PbSe has unique and outstanding characteristics: it can detect IR radiation of wavelengths from 1.5 to 5.2 μm (mid-wave infrared window, abbreviated MWIR – in some special conditions it is possible to extend its response beyond 6 μm), it has a high detectivity at room temperature (uncooled performance), and due to its quantum nature, it also presents a very fast response, which makes this material an excellent candidate as detector of low cost high speed infrared imagers.[12]. The products of electrolysing lead bromide are lead metal and bromine gas. You can electrolyse molten compounds as long as they are ionic compounds, so that on melting there free ions to move to carry the current to facilitate the electrolysis process of splitting the compound into its constituent elements. [16], Except where otherwise noted, data are given for materials in their, Methods to manufacture PbSe infrared detectors, "High-temperature thermoelectric performance of heavily doped PbSe", "Study of the Thermoelectric Properties of Lead Selenide Doped with Boron, Gallium, Indium, or Thallium", National Pollutant Inventory - Lead and Lead Compounds Fact Sheet, https://en.wikipedia.org/w/index.php?title=Lead_selenide&oldid=996499833, Articles containing unverified chemical infoboxes, Articles with unsourced statements from February 2007, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 December 2020, at 23:55.

Stannic Selenide. Since then, PbSe has been commonly used as an infrared photodetector in multiple applications, from spectrometers for gas and flame detection to infrared fuzes for artillery ammunition or Passive Infrared Cueing systems (PICs). Even though it has been extensively studied, today the mechanisms responsible of its high detectivity at room temperature are not well understood. Solubility Product Constants near 25 °C. The following are a good mix of naming and formula writing problems to help you get some practice. MODULE 4 UNIT 1 Assignment Part A This assignment is to be sent to your instructor for evaluation. Compare Products: Select up to 4 products. 1. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. The mineral clausthalite is a naturally occurring lead selenide. In fact, this has been the most important milestone in the last decades concerning the manufacturing of PbSe detectors, as it has opened the technology to the market of uncooled MWIR high-resolution imaging cameras with high frame rates and reduced costs. NOTE: ALL NUMBERS IN FORMULAS SHOULD BE WRITTEN AS SUBSCRIPTS. Formula and structure: Lead sulfide chemical formula is PbS and its molar mass is 239.26 g mol-1.Lead sulfide is formed by the cation Pb +2 (the lesser oxidized ion of Pb) and the anion S-2 (the lesser oxidizer ion of S). Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. It is used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. Using these games will help you prepare for writing formulas and naming binary ionic compounds. It is a heavy metal that is denser than most common materials. In contrast to the polycrystalline material based detectors other solution processing techniques like spin-coating are applied. The common system uses two suffixes (-ic and -ous) that are appended to the stem of the element name.The -ic suffix represents the greater of the two cation charges, and the -ous suffix represents the … 45 nm and their length was up to 1100 nm, for nanotubes the diameter was 50 nm and the length up to 2000 nm.[5]. CBD method has been extensively used during last decades and is still used for processing PbSe infrared detectors. This activity includes every compound formula and name that can be formed from the list 44 Ions provided in Chemistry A at Pickerington High School Central. The diameter of the nanorods were approx. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. [citation needed], Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. *Please select more than one item to compare "PbO"_2 This is also sometimes called lead dioxide. 7 lead(IV) oxide 32 copper bromide 8 zinc nitride 33 sodium nitride 9 silver iodide 34 silver chloride 10 barium fluoride 35 sodium hydride 11 lead(II) iodide 36 potassium nitride 12 … Write the element symbol for Lead. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) This method has an intrinsic advantage compared with the CBD method, which is the compatibility with preprocessed substrates, like silicon CMOS-technology wafers, and the possibility of processing complex detectors, such as the focal plane arrays for imagers. The (IV) indicates that lead is in the 4+ oxidation state in this compound. Lead (IV) Acetate, also known as lead tetraacetate, is a colourless solid that has a chemical formula of Pb(C 2 H 3 O 2) 4.It is easily degraded by moisture and is typically stored with extra acetic acid. chemical formula that corresponds to the name Name Formula 1) NaF 13) potassium fluoride ... cobalt (II) selenide is CoSe 20) silver cyanide is AgCN 21) copper (II) bicarbonate is Cu(HCO 3)2 22) iron (II) oxide is FeO 23) lithium cyanide is LiCN 24) lead (IV) sulfite is Pb(SO 3)2.
