Lead selenide (PbSe)

Description:
Lead selenide (PbSe) is a semiconductor material known for its narrow bandgap, which makes it particularly useful in infrared applications. It appears as a black or dark gray solid and is typically synthesized through various methods, including chemical vapor deposition and solid-state reactions. PbSe exhibits high electron mobility and is sensitive to infrared radiation, making it valuable in photodetectors and thermophotovoltaic devices. The compound crystallizes in a rock-salt structure, and its properties can be influenced by factors such as temperature and doping with other elements. Lead selenide is also notable for its relatively high thermal stability and can be used in high-temperature applications. However, it is important to handle PbSe with care due to the toxicity of lead and selenium, both of which pose environmental and health risks. Proper safety measures should be taken when working with this compound in laboratory or industrial settings.
