· JVASP-41445· TmCuPbSe3

TmCuPbSe3 is a ternary compound semiconductor composed of thulium, copper, lead, and selenium, representing an emerging materials system in chalcogenide research. This compound belongs to the family of lead-based selenides and is primarily investigated for thermoelectric and photovoltaic applications, where the combination of heavy elements and mixed-valence chemistry can enable favorable charge carrier properties and phonon scattering. As a research-stage material, TmCuPbSe3 is notable for potential use in solid-state thermal energy conversion and infrared optoelectronics, where engineers seek materials with tunable electronic structure and reduced thermal conductivity relative to conventional metallic alternatives.

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.
