Lead selenide (direct bandgap of 0.27 eV at room temperature. (Note that[1] 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 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 4-4.7 µm.[citation needed]

polycrystalline nanotubes of lead selenide were synthesized via controlled organism membranes. The diameter of the nanorods is approx. 45 nm and their length is up to 1100 nm, for nanotubes the diameter is 50 nm and the length up to 2000 nm. [1]

Lead selenide nanocrystals embedded into various materials can be used as quantum dots, for example in nanocrystal solar cells.

The clausthalite is a naturally occurring lead selenide.
