· TmYO3

TmYO3 is a rare-earth oxide ceramic compound composed of thulium and yttrium oxides, belonging to the family of lanthanide-based semiconducting oxides. This material is primarily investigated in research contexts for optoelectronic and photonic applications, where its rare-earth dopant characteristics enable luminescence and energy conversion functions. TmYO3 is notable for potential use in solid-state laser systems, scintillators, and radiation detection devices, where the thulium dopant can provide efficient energy transfer and emission in the infrared region; it represents an emerging choice for specialized photonic applications where conventional semiconductors are less suitable.
