· Pr2S3

Praseodymium sesquisulfide (Pr₂S₃) is a rare-earth metal chalcogenide semiconductor compound combining praseodymium with sulfur. This material belongs to the lanthanide sulfide family and is primarily of research and exploratory interest rather than established in high-volume commercial production. Pr₂S₃ is investigated for optoelectronic devices, photocatalytic applications, and as a dopant or additive in advanced ceramic and thin-film systems where rare-earth semiconductors offer tunable electronic properties and potential luminescent behavior.
