PURPOSE:To inhibit drop in flux during use by coating the surface of the fluorescent material particles with silicon oxide. CONSTITUTION:A solution containing organic silicon is mixed with a fluorescent material or with a fluorescent material suspension. The mixture is heat-treated to coat the surface of the fluorescent material particles with silicon oxide. A fluorescent lamp is manufactured by applying the fluorescent material on the inner surface of a tube. According to this method, silicon oxide film is formed on the surface of the particle stably, and furthermore, a fluorescent lamp characterized by greatly inhibited flux drop is obtained. |
