· JVASP-107098· Tm2TeO2

Tm2TeO2 is a rare-earth tellurite ceramic compound combining thulium oxide with tellurium oxide, belonging to the family of tellurite-based ceramics. This is a research-phase material primarily explored for optical and photonic applications rather than established industrial production. The tellurite ceramic family is notable for high refractive index and infrared transparency, making these compounds candidates for advanced optical components, infrared optics, and potentially scintillation or laser host materials—though Tm2TeO2 specifically remains in exploratory research rather than commercial deployment.
