· Li2 As2 Se4

Li2As2Se4 is a quaternary chalcogenide ceramic compound combining lithium, arsenic, and selenium elements, belonging to the family of ionic crystalline materials used in solid-state and photonic applications. This material is primarily investigated in research contexts for infrared optics, solid-state electrolytes, and semiconductor device applications where its unique combination of ionic conductivity and optical transparency in the infrared spectrum is exploited. While not yet widely deployed in high-volume industrial production, Li2As2Se4 and related lithium chalcogenides show promise as alternatives to conventional optical glasses and ceramic electrolytes in emerging energy storage and photonic technologies.
