Ho1 Bi2 Cl1 O4
semiconductor· Ho1 Bi2 Cl1 O4
Ho₁Bi₂Cl₁O₄ is a rare-earth bismuth oxyhalide semiconductor, a mixed-valence compound combining holmium and bismuth with chloride and oxide anions. This material belongs to an emerging class of layered halide perovskites and bismuth-based semiconductors being investigated for optoelectronic and photocatalytic applications. Currently in the research phase rather than established in high-volume manufacturing, this compound shows promise in the broader family of lead-free semiconductors due to its potential for tunable bandgap and photocatalytic activity under visible light.
