Idealized equations for these two steps are:[7]. A PbS element can be used to measure radiation in either of two ways: by measuring the tiny photocurrent the photons cause when they hit the PbS material, or by measuring the change in the material's electrical resistance that the photons cause. Pb[Fe(CN)6] (Plumbic ferocynide) If you need more so you can also make it; See, Lead makes to ions; Pb++ ion (Plumbous ion) and, Pb++++ ion (Plumbic ion) So, with the help of this and many other ions, you can make more compounds containing lead thats all !!

Cooling the PbS elements, for example using liquid nitrogen or a Peltier element system, shifts its sensitivity range to between approximately 2 and 4 μm. 3 Solutions of sulfide salts are corrosive. A dictionary file. [12] As an infrared detector, PbS functions as a photon detector, responding directly to the photons of radiation, as opposed to thermal detectors, which respond to a change in detector element temperature caused by the radiation. Write the chemical formula for each ionic compound below. Addition of hydrogen sulfide or sulfide salts to a solution containing a lead salt, such as PbCl2, gives a black precipitate of lead sulfide. Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions.
