· JVASP-1804· KPrS2

KPrS₂ is a rare-earth sulfide ceramic compound containing potassium and praseodymium, representing a member of the layered metal chalcogenide family. This material is primarily investigated in research contexts for optical, electronic, and photocatalytic applications where rare-earth dopants and sulfide matrices offer tunable band gaps and light-responsive properties. KPrS₂ and related compounds are of interest in advanced ceramics research for potential use in photocatalysis, optoelectronics, and materials screening for next-generation energy conversion devices, though industrial deployment remains limited compared to conventional oxides and nitrides.
