· JVASP-29411· Tm2Te5O13

Tm2Te5O13 is a rare-earth tellurite ceramic compound combining thulium oxide with tellurium oxide components, belonging to the family of mixed-metal tellurate ceramics. This material is primarily of research interest in optical and photonic applications, where tellurite-based ceramics are valued for their high refractive index, infrared transparency, and potential as host matrices for rare-earth dopants in laser and fiber optic technologies. Its notable advantage over conventional silicate ceramics is enhanced optical performance in the mid-infrared spectrum, making it relevant for specialized photonic devices rather than traditional structural or thermal applications.
