· 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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
