The diameter of the nanorods were approx. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. 3) gallium selenide Ga 2 Se 3 4) strontium iodide SrI 2 5) titanium (IV) fluoride TiF 4 6) silver hydroxide AgOH 7) lead (IV) perchlorate Pb(ClO 4) 4 8) zinc hydride ZnH 2 9) potassium chromate K 2 CrO 4 10) iron (III) oxalate Fe 2 (C 2 O 4) 3 11) copper (II) bisulfate Cu(HSO 4) 2 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 … In fact, lead sulfide was one of the earliest materials to be used as a semiconductor. Use the Common Ion Table to find the formula and charge for the sulfate ion. 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. Even though it has been extensively studied, today the mechanisms responsible of its high detectivity at room temperature are not well understood. The mineral clausthalite is a naturally occurring lead selenide. It does not require cooling, but performs better at lower temperatures. The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. Chemical Formula Writing Worksheet Write chemical formulas for the compounds in each box. Write the formula for each of the following compounds: a. zinc chloride b. tin(IV) fluoride c. calcium nitride d. aluminum sulfide e. mercury(I) selenide f. silver iodide. Structure, properties, spectra, suppliers and links for: Lead(IV) fluoride, Lead tetrafluoride. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. 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. The products of electrolysing lead bromide are lead metal and bromine gas. [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]. It is a heavy metal that is denser than most common materials.

A major process involves smelting of PbS followed by reduction of the resulting oxide. 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. 5. 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 new processing method has been recently developed in Spain. 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.

It may be formed by direct reaction between its constituent elements, lead and selenium. InChI=1S/Pb/q+4 Using these games will help you prepare for writing formulas and naming binary ionic compounds. Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. Lead selenide is a photoconductor material. [14] It is based on the deposition of the active material by thermal evaporation, followed by specific thermal treatments. 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). 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. 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. [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. Ioffe Institute in Russia. It is a grey crystalline solid material. [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. 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. Stannic Selenide. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.)
