· YErO3

Yttrium erbium oxide (YErO3) is a mixed rare-earth oxide semiconductor belonging to the family of lanthanide-based functional ceramics. This material is primarily of research and specialized industrial interest, explored for its potential in optoelectronic devices, thermal barrier coatings, and solid-state laser host materials where the combination of rare-earth dopants offers tunable electronic and optical properties. Its notable advantage over single rare-earth oxides lies in the ability to engineer electronic band structure and luminescence characteristics through mixed lanthanide composition, making it particularly relevant in applications requiring precision control of light emission or thermal management in extreme environments.

Regulatory Screening

Environmental

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.
