· K(GeSe2)2

K(GeSe₂)₂ is a potassium germanium selenide compound belonging to the chalcogenide semiconductor family, characterized by a layered crystal structure combining alkali metals with group IV–VI elements. This is primarily a research material explored for its nonlinear optical properties and potential in infrared photonics applications, particularly where mid-infrared transparency and frequency conversion are required. The material represents an emerging alternative in the broader class of chalcogenide glasses and crystals, which are valued for their extended infrared transmission range compared to conventional oxide-based optics.
