Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. (Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) [3] A grey solid, it is used for manufacture of infrared detectors for thermal imaging.[4] The mineral clausthalite is a naturally occurring lead selenide.
It may be formed by direct reaction between its constituent elements, lead and selenium.
