· Ho4 Bi4 O14

Ho₄Bi₄O₁₄ is a mixed rare-earth and bismuth oxide ceramic compound that functions as a semiconductor material. This is primarily a research-phase material belonging to the family of complex oxide semiconductors, studied for its potential electronic and photonic properties arising from the combination of holmium (rare-earth element) and bismuth oxide phases. While industrial deployment remains limited, materials in this class are investigated for photocatalytic applications, scintillation detection, and advanced optoelectronic devices where the rare-earth dopant and bismuth oxide matrix can enable tunable bandgaps and light emission properties.
