Abstract
A light-transmissive and transparent film photocatalyst made of one of anatase-type titanium dioxide and alpha iron oxide is formed on an outside surface of a glass tube used for a fluorescent lamp. The thin film photocatalyst is formed so that electrons and holes generated inside the film by light irradiation can easily and rapidly move to the surface of the film and generate various active species at the surface of the film by contacting with the room air, enabling an excellent deodorization effect, bactericidal and fungicidal activity and contamination preventing effect.
