· Er2 S2 Cl2

Er₂S₂Cl₂ is a rare-earth chalcogenide halide semiconductor compound combining erbium, sulfur, and chlorine, representing an emerging material in the semiconductor research space rather than a commercially established engineering material. This compound belongs to the family of mixed-anion rare-earth materials being investigated for potential optoelectronic and photonic applications, particularly due to erbium's relevance in fiber-optic communications and its luminescent properties. While primarily in the research phase, materials of this class are of interest to researchers exploring novel band-gap engineering, solid-state lighting, and integrated photonics where erbium's 1.5 μm emission window aligns with telecommunications wavelengths.

Export Control

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.
