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]. Tin(IV) Selenide SnSe2 Molar Mass, Molecular Weight. Stannic Selenide. The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. 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. 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. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. [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]. [7] Several groups have since reported thermoelectric figures of merit exceeding unity, which is the characteristic of a high performance thermoelectric.[8][9][10]. For Lead (IV) sulfate we have a transition metal and a polyatomic ion. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. See more Lead products.

Lead selenide is a photoconductor material. CopyCopied, CSID:10644804, http://www.chemspider.com/Chemical-Structure.10644804.html (accessed 16:10, Jan 15, 2021) 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 mineral clausthalite is a naturally occurring lead selenide. The diameter of the nanorods were approx. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is used for manufacture of infrared detectors for thermal imaging,[4] operating at wavelengths between 1.5–5.2 μm. Structure, properties, spectra, suppliers and links for: Lead(IV) fluoride, Lead tetrafluoride. Chemical bath disposition (CBD) is the standard manufacturing method. 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. 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.
