ZnSe, or zinc selenide, is a compound made of zinc and selenium. It is a semiconductor material commonly used in optoelectronic devices, such as light-emitting diodes (LEDs) and laser diodes. ZnSe has a wide bandgap, which allows it to emit light in the visible and ultraviolet ranges. In addition to its use in electronics, ZnSe is also employed in optical applications, including lenses and windows for infrared systems. Its unique properties make it valuable in various fields, including telecommunications and medical imaging, where efficient light transmission is essential.
