Cu3PSe2S2
metal· JVASP-122486· Cu3PSe2S2
Cu3PSe2S2 is a quaternary chalcogenide compound combining copper with phosphorus, selenium, and sulfur—a mixed-anion semiconductor material in the emerging class of multinary metal chalcogenides. This is primarily a research-phase material under investigation for optoelectronic and thermoelectric applications, rather than an established industrial product; the material family shows promise for photovoltaic absorbers, solid-state radiation detection, and energy conversion devices where tunable bandgap and mixed-anion chemistry offer advantages over conventional binary or ternary semiconductors.

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.
