Paper Abstract

A p-type semiconducting metallic-oxide film is provided in a CO gas atmosphere, and the light is irradiated onto the film, in this system, the light transmission factor depends on the gas concentration. Utilizing this principle, the optical response of this system to CO gas was studied. As the result, it was found that NiCo2O4 gave the maximum light transmission intensity change.
