lead iv selenide formula

These photons are absorbed inside the PbSe micro-crystals causing then the promotion of electrons from the valence band to the conduction band. 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 electrolysis of molten lead(II) bromide. MODULE 4 UNIT 1 Assignment Part A This assignment is to be sent to your instructor for evaluation. [14] It is based on the deposition of the active material by thermal evaporation, followed by specific thermal treatments. CopyCopied, CSID:10644804, http://www.chemspider.com/Chemical-Structure.10644804.html (accessed 16:10, Jan 15, 2021) 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. The (IV) tells us that Lead has a charge of +4. I am trying to balance a chemical equation. It does not require cooling, but performs better at lower temperatures. [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. NOTE: ALL NUMBERS IN FORMULAS SHOULD BE WRITTEN AS SUBSCRIPTS. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. What is widely accepted is that the material and the polycrystalline nature of the active thin film play a key role in both the reduction of the Auger mechanism and the reduction of the dark current associated with the presence of multiple intergrain depletion regions and potential barriers inside the polycrystalline thin films. This new processing method has been recently developed in Spain. 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). PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. Ioffe Institute in Russia. In contrast to the polycrystalline material based detectors other solution processing techniques like spin-coating are applied. 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. 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. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. [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]. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. Lead (atomic symbol: Pb, atomic number: 82) is a Block P, Group 14, Period 6 element with an atomic radius of 207.2. Since oxygen almost always has an oxidation state of 2-, we use simple mathematics to yield a net oxidation state of 0: overbrace((4))^"Pb" + overbrace((x)(-2))^"O" = 0 x = color(red)(2 There is thus one lead atom and two oxygen atoms per compound of lead(IV) oxide. [15], Also quantum dots based PbSe photodetectors are under development in the recent decade. Lead selenide is a photoconductor material.

(Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) [3] It is a grey crystalline solid material. Its detection mechanism is based on a change of conductivity of a polycrystalline thin-film of the active material when photons are incident. 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. 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 … 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.

For Lead (IV) sulfate we have a transition metal and a polyatomic ion. A major process involves smelting of PbS followed by reduction of the resulting oxide.

Lead sulfide crystallizes in the sodium chloride motif, unlike many other IV-VI semiconductors. Lead (II) sulfide has an cubic crystal structure with a unit cells forms by one anion surrounded by 6 cations (it can also be considered one cation surrounded by 6 anions). It is a grey crystalline solid material. Stannic Selenide. 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). Write the element symbol for Lead. Tin(IV) Selenide SnSe2 Molar Mass, Molecular Weight. The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. Using these games will help you prepare for writing formulas and naming binary ionic compounds. *Please select more than one item to compare 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. The material was identified as a potential high temperature thermoelectric with sodium or chlorine doping by Alekseva and co-workers at the A.F. [citation needed], Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. Compare Products: Select up to 4 products. The products of electrolysing lead bromide are lead metal and bromine gas. Since PbS is the main ore of lead, much effort has focused on its conversion. [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. "PbO"_2 This is also sometimes called lead dioxide. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. The following are a good mix of naming and formula writing problems to help you get some practice. The mineral clausthalite is a naturally occurring lead selenide. 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 (IV) indicates that lead is in the 4+ oxidation state in this compound. It is used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. Even though it has been extensively studied, today the mechanisms responsible of its high detectivity at room temperature are not well understood. Chemical bath disposition (CBD) is the standard manufacturing method. Search results for lead powder at Sigma-Aldrich.

Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it. CBD method has been extensively used during last decades and is still used for processing PbSe infrared detectors. Ionic Compound Formula K sp. Subsequent theoretical work at Oak Ridge National Laboratory, USA predicted that its p-type performance could equal or exceed that of the sister compound, lead telluride.
