· JVASP-121434· K2Zn3S4

K2Zn3S4 is a ternary sulfide ceramic compound belonging to the thiospinel family, combining potassium, zinc, and sulfur in a crystalline structure. This material is primarily of research interest for optoelectronic and photocatalytic applications, where its sulfide-based composition offers band gap properties suited to visible-light absorption and semiconductor device development. While not yet established in mainstream industrial production, materials in this thiospinel class are being investigated for photocatalysis, solid-state lighting, and next-generation solar conversion technologies where conventional oxides are insufficient.
