It is used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. The number of electrons in each of Lead's shells is [2, 8, 18, 32, 18, 4] and its electron configuration is [Xe] 4f 14 5d 10 6s 2 6p 2.The lead atom has a radius of 175 pm and a Van der Waals radius of 202 pm. The diameter of the nanorods were approx. 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). CopyCopied, CSID:10644804, http://www.chemspider.com/Chemical-Structure.10644804.html (accessed 16:10, Jan 15, 2021) PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. It is a grey crystalline solid material. This new processing method has been recently developed in Spain. A major process involves smelting of PbS followed by reduction of the resulting oxide. The material was identified as a potential high temperature thermoelectric with sodium or chlorine doping by Alekseva and co-workers at the A.F. In fact, lead sulfide was one of the earliest materials to be used as a semiconductor. 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]. 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. It is a heavy metal that is denser than most common materials. The (IV) tells us that Lead has a charge of +4. 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. For Lead (IV) sulfate we have a transition metal and a polyatomic ion. Use the Common Ion Table to find the formula and charge for the sulfate ion.

Stannic Selenide. [14] It is based on the deposition of the active material by thermal evaporation, followed by specific thermal treatments. 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. Lead selenide is a thermoelectric material. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material.

In contrast to the polycrystalline material based detectors other solution processing techniques like spin-coating are applied. [citation needed], Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it.

The mineral clausthalite is a naturally occurring lead selenide. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) Tin(IV) Selenide SnSe2 Molar Mass, Molecular Weight. Since PbS is the main ore of lead, much effort has focused on its conversion. 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. Write the element symbol for Lead. NOTE: ALL NUMBERS IN FORMULAS SHOULD BE WRITTEN AS SUBSCRIPTS. 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 [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. Formula: It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. *Please select more than one item to compare Lead selenide is a photoconductor material. [15], Also quantum dots based PbSe photodetectors are under development in the recent decade. "PbO"_2 This is also sometimes called lead dioxide. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. 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. InChI=1S/Pb/q+4 I am trying to balance a chemical equation. Chemical Formula Writing Worksheet Write chemical formulas for the compounds in each box. These photons are absorbed inside the PbSe micro-crystals causing then the promotion of electrons from the valence band to the conduction band.

It may be formed by direct reaction between its constituent elements, lead and selenium. The following are a good mix of naming and formula writing problems to help you get some practice. 5. CopyCopied, TYDJWWAXVOMTQR-UHFFFAOYSA-N See more Lead products. Solubility Product Constants near 25 °C. 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. [3] It is a grey crystalline solid material. 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. Plumbic Selenide. Ionic Compound Formula K sp. Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. 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. The electrolysis of molten lead(II) bromide. 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 … Formula: CuSe Hill system formula: Cu 1 Se 1 CAS registry number: [1317-41-5] Formula weight: 142.506 Class: selenide Colour: blue-black Appearance: crystalline solid Melting point: 550°C (decomposes) Boiling point: Density: 6000 kg m-3 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. Formula: lead(IV) sulfate is a product. [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 peak sensitivity depends on temperature and varies between 3.7–4.7 μm. It does not require cooling, but performs better at lower temperatures. Chemical bath disposition (CBD) is the standard manufacturing method. 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). Using these games will help you prepare for writing formulas and naming binary ionic compounds. 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).
