SmTmO3
semiconductor· SmTmO3
SmTmO3 is a rare-earth oxide ceramic compound composed of samarium and thulium in a perovskite or related oxide crystal structure. This material is primarily investigated in research contexts for applications requiring high refractive index, thermal stability, or unique optical properties enabled by rare-earth doping. While not yet widespread in production engineering, rare-earth oxides like SmTmO3 are of interest for advanced ceramics, photonic devices, and high-temperature applications where conventional oxides reach performance limits.

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.
