· JVASP-26335· TmBi2BrO4

TmBi2BrO4 is an ternary bismuth oxide halide ceramic compound containing thulium, belonging to the layered perovskite family. This is a research-phase material under investigation for photocatalytic and optoelectronic applications, where its mixed-anion framework offers potential for tuning band gaps and photon absorption compared to conventional binary oxides. The material's notably dense crystal structure and moderate elastic stiffness make it of interest in solid-state chemistry and materials physics, though industrial-scale applications remain limited to specialized research and development contexts.
