EuTlS2

ceramic

· JVASP-85134· EuTlS2

EuTlS2 is a ternary chalcogenide ceramic compound combining europium, thallium, and sulfur in a layered crystal structure. This is primarily a research material investigated for its electronic and optical properties rather than a widely commercialized engineering ceramic. The material family shows promise in semiconductor applications and solid-state physics, with potential interest in thermoelectric devices, optical sensors, or specialized photonic systems where the unique combination of rare-earth (Eu) and post-transition metal (Tl) elements offers tunable electronic band structure.

Regulatory Screening

Environmental

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.
