· Cs2NaInF6

Cs2NaInF6 is an inorganic fluoride ceramic compound belonging to the elpasolite family of double perovskites, characterized by a complex crystal structure incorporating cesium, sodium, indium, and fluoride ions. This material is primarily investigated in research contexts for optoelectronic and photonic applications, particularly as a potential host matrix for rare-earth dopants in scintillators, phosphors, and solid-state laser media. Its notable advantages over conventional alternatives include good optical transparency in the visible and near-infrared regions, chemical stability, and the ability to accommodate various luminescent centers, making it of interest for radiation detection and advanced lighting applications in emerging technologies.

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.
