· Li0.2Na0.8AsSe2

Li₀.₂Na₀.₈AsSe₂ is a mixed-cation chalcogenide semiconductor combining lithium, sodium, arsenic, and selenium in a solid-solution structure. This is a research-phase compound belonging to the arsenic chalcogenide family, explored primarily for its potential in infrared optics, nonlinear optical applications, and solid-state ion-conducting devices where the mixed alkali-metal composition may tune bandgap, phonon modes, or ionic mobility compared to single-cation analogs.

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.
