Bi₁₂TiO₂₀ is a bismuth titanate ceramic compound belonging to the sillenite family of semiconductors, characterized by a cubic crystal structure with photorefractive properties. It is primarily used in optical and optoelectronic applications where light-induced refractive index changes are required, including holographic recording, optical storage, and dynamic optical modulation devices. This material is notable for its strong photorefractive effect at visible and near-infrared wavelengths, making it competitive with alternatives like photorefractive polymers and lithium niobate in applications requiring reversible, non-destructive optical data manipulation.
