· JVASP-3990· ErSeI

ErSeI is a ternary ceramic compound composed of erbium, selenium, and iodine, representing a layered halide perovskite material under active research. This material falls within the family of rare-earth halides and is primarily investigated for optoelectronic and photonic applications rather than structural engineering roles. ErSeI and related compounds are of interest to researchers exploring next-generation semiconductors, particularly for applications requiring tunable bandgaps, radiation detection, or novel light-emitting devices, though it remains largely in the experimental/laboratory phase rather than established industrial production.

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.
