What is Lead Selenide used for?
What is Lead Selenide used for?
It is used for manufacture of infrared detectors for thermal imaging, operating at wavelengths between 1.5–5.2 μm. 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.
What is the formula for Lead II selenide?
PbSeLead selenide / Formula
How does PBS detector work?
PbSe detectors have a particularly strong inner photoelectric effect, so that the resistance is reduced when infrared light reaches the detector. They can be used when uncooled at wavelengths up to 4.7 µm. At room temperature, they demonstrate a detectivity (D*) of greater than 1010.
Is lead sulfide toxic?
It is also known as galena, which is the principal ore and important compound of lead. It is one of the earliest materials to be used as a semiconductor as it tends to crystallize in sodium chloride. Lead sulfide is toxic if it is heated to decomposition, which forms lead and sulfur oxides.

What is INSB detector?
High-speed, low-noise infrared detectors capable of detecting infrared light up to approximately 3.5 μm.
Is lead sulfide good for eyes?
These findings offer reasonable justification to conclude that kohl containing lead sulfide as a major ingredient has a natural protective effect against the sun’s glare when applied to the eyes in the form of kohl and thus support claims and uses reported elsewhere.
Is lead a carcinogen?
The Department of Health and Human Services (HHS) has determined that lead and lead compounds are reasonably anticipated to be human carcinogens (causing cancer in people). The U.S. Environmental Protection Agency (EPA) has classified lead as a probable human carcinogen.
What is CSF made from?
Contents. CSF is derived from blood plasma and is largely similar to it, except that CSF is nearly protein-free compared with plasma and has some different electrolyte levels. Due to the way it is produced, CSF has a higher chloride level than plasma, and an equivalent sodium level.
What is InSb material?
Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb). It is a narrow-gap semiconductor material from the III-V group used in infrared detectors, including thermal imaging cameras, FLIR systems, infrared homing missile guidance systems, and in infrared astronomy.
