Bi12SiO20
semiconductor· Bi12SiO20
Bi12SiO20 is a bismuth silicate ceramic compound belonging to the Aurivillius family of layered perovskites, characterized by a high refractive index and photorefractive properties. It is primarily used in electro-optic and photonic applications, particularly in holographic storage, nonlinear optical devices, and spatial light modulation systems where its ability to respond to light patterns under applied electric fields is advantageous. Engineers select this material over conventional alternatives when requirements demand materials combining transparency in the visible to infrared range with strong photorefractive response and electrical tunability.
