· TbSmO3

TbSmO3 is a mixed rare-earth oxide ceramic compound combining terbium and samarium oxides, belonging to the rare-earth semiconductor family. This material is primarily investigated in research contexts for applications requiring high refractive index, thermal stability, and optical properties characteristic of rare-earth ceramics. Its potential extends to optoelectronic devices, photonic materials, and specialized high-temperature semiconductor applications where conventional semiconductors are insufficient.
