Lead selenide (PbSe) 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 incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.)  It is a grey crystalline solid material.
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.
Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. The diameter of the nanorods were approx. 45 nm and their length was up to 1100 nm, for nanotubes the diameter was 50 nm and the length up to 2000 nm.
Lead selenide nanocrystals embedded into various materials can be used as quantum dots, for example in nanocrystal solar cells.
Lead selenide is a thermoelectric material. The material was identified as a potential high temperature thermoelectric with sodium or chlorine doping by Alekseva and co-workers at the A.F. Ioffe Institute in Russia. 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.Several groups have since reported thermoelectric figures of merit exceeding unity, which is the characteristic of a high performance thermoelectric.
The mineral clausthalite is a naturally occurring lead selenide.
It may be formed by direct reaction between its constituent elements (lead and selenium).
