Tm1 Bi2 Br1 O4
semiconductor· Tm1 Bi2 Br1 O4
Tm₁Bi₂Br₁O₄ is an experimental mixed-metal oxyhalide semiconductor combining thulium, bismuth, bromine, and oxygen in a layered or complex crystal structure. This compound belongs to the broader family of halide perovskites and bismuth-based semiconductors, which are actively researched for next-generation optoelectronic and photovoltaic applications due to their tunable bandgaps and potential lead-free stability. The inclusion of thulium (a rare-earth element) suggests potential applications in photoluminescence, infrared sensing, or specialty optical devices where rare-earth doping provides enhanced functionality.
