Use the Common Ion Table to find the formula and charge for the sulfate ion. For Lead (IV) sulfate we have a transition metal and a polyatomic ion. Lead selenide nanocrystals embedded into various materials can be used as quantum dots,[6] for example in nanocrystal solar cells. "PbO"_2 This is also sometimes called lead dioxide. 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. (Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) Ioffe Institute in Russia. Write the element symbol for Lead. 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). This new processing method has been recently developed in Spain. It is a heavy metal that is denser than most common materials. 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].

(Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) 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. I am trying to balance a chemical equation. 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). The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. Do I write Pb2(SO4)4 or Pb(SO4)2 (obviously, the mumbers will be in subscript) Thanks so much:) [15], Also quantum dots based PbSe photodetectors are under development in the recent decade. The following are a good mix of naming and formula writing problems to help you get some practice. The (IV) indicates that lead is in the 4+ oxidation state in this compound. The material was identified as a potential high temperature thermoelectric with sodium or chlorine doping by Alekseva and co-workers at the A.F. 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 used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. Tin(IV) Selenide SnSe2 Molar Mass, Molecular Weight. Two methods are commonly used nowadays to manufacture infrared detectors based on PbSe. A major process involves smelting of PbS followed by reduction of the resulting oxide. It may be formed by direct reaction between its constituent elements, lead and selenium. 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.
