· JVASP-49816· Er2TeO2

Er2TeO2 is an erbium tellurite ceramic compound that combines rare-earth erbium with tellurium oxide, forming a dense crystalline oxide material. This compound is primarily investigated in research contexts for photonic and optical applications, particularly in infrared transmission windows and as a potential host material for rare-earth dopants in fiber amplifiers and laser systems. Its tellurite base makes it notable within the broader family of tellurite glasses and ceramics, which are valued for broad infrared transparency and favorable rare-earth ion incorporation compared to traditional silicate alternatives.

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.
