Since PbS is the main ore of lead, much effort has focused on its conversion. 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. Tin(IV) Selenide SnSe2 Molar Mass, Molecular Weight. Provided below is a list of the chemical formulas of some common chemical compounds (along with their molecular weights). 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. 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. See more Lead products. 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]. 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. 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. (Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) Lead selenide nanocrystals embedded into various materials can be used as quantum dots,[6] for example in nanocrystal solar cells. Lead sulfide crystallizes in the sodium chloride motif, unlike many other IV-VI semiconductors. [citation needed], Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. 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 used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. It does not require cooling, but performs better at lower temperatures. The material was identified as a potential high temperature thermoelectric with sodium or chlorine doping by Alekseva and co-workers at the A.F. CBD method has been extensively used during last decades and is still used for processing PbSe infrared detectors. InChI=1S/Pb/q+4 CopyCopied, CSID:10644804, http://www.chemspider.com/Chemical-Structure.10644804.html (accessed 16:10, Jan 15, 2021) Write the formula for each of the following compounds: a. sodium oxide b. sodium peroxide c. potassium cyanide d. copper(II) nitrate e. selenium tetrabromide f. iodous acid g. lead(IV) sulfide h. copper(I) chloride i. gallium arsenide j. cadmium selenide k. zinc sulfide l. nitrous acid m. diphosphorus pentoxide PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. The mineral clausthalite is a naturally occurring lead selenide. The (IV) tells us that Lead has a charge of +4. The diameter of the nanorods were approx. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. Stannic Selenide.

Formula: [7] Several groups have since reported thermoelectric figures of merit exceeding unity, which is the characteristic of a high performance thermoelectric.[8][9][10]. [14] It is based on the deposition of the active material by thermal evaporation, followed by specific thermal treatments. Lead selenide is a photoconductor material. 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. 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. [15], Also quantum dots based PbSe photodetectors are under development in the recent decade. In fact, lead sulfide was one of the earliest materials to be used as a semiconductor. 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. 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. Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it. (Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) [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]. Formula: These photons are absorbed inside the PbSe micro-crystals causing then the promotion of electrons from the valence band to the conduction band. 1. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. 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). [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. It may be formed by direct reaction between its constituent elements, lead and selenium. CopyCopied, TYDJWWAXVOMTQR-UHFFFAOYSA-N The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. Plumbic Selenide. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. 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. Use the Common Ion Table to find the formula and charge for the sulfate ion. Solubility Product Constants near 25 °C.
