Description

Technical field [0001] The invention belongs to the field of ceramic materials, and particularly relates to a photosensitive ceramic material and a preparation method thereof. Background technique [0002] Semiconductor ceramics refer to the characteristics of semiconductors and conductivity of about 10 -6 ~10 5 S / m ceramics. The electrical conductivity of semiconductor ceramics changes significantly due to changes in external conditions (temperature, light, electric field, atmosphere, temperature, etc.). Therefore, changes in physical quantities in the external environment can be converted into electrical signals to make sensitive components for various purposes. Semiconductor ceramics mainly include heat sensitive ceramics, photosensitive ceramics, gas sensitive ceramics and humidity sensitive ceramics. Among them, photosensitive ceramics are mainly semiconductor ceramics, and their conductive mechanism is divided into intrinsic light guide and impurity light guide. For intri...
