· Hg3 Se3

Hg₃Se₃ is an experimental mercury selenide compound belonging to the family of mercury chalcogenides, which are narrow-bandgap semiconductors of interest primarily in research rather than established commercial production. This material is investigated for potential applications in infrared optics and sensing due to the favorable optical properties characteristic of mercury-based chalcogenides, though it remains largely confined to fundamental materials research and has not achieved widespread engineering adoption compared to more mature infrared semiconductor alternatives.
