· JVASP-123210· Er3I

Er₃I is an erbium iodide ceramic compound belonging to the rare-earth halide family, characterized by ionic bonding between trivalent erbium and iodide ions. This material is primarily investigated in research contexts for photonic and optical applications, leveraging erbium's strong absorption and emission properties in the infrared spectrum, particularly near the telecommunications wavelength of 1.55 μm. Er₃I and related rare-earth halides are of interest for upconversion phosphors, laser host materials, and infrared optical components where thermal stability and optical clarity in the near-infrared are valued.

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.
