Abstract
PURPOSE: To prevent darkening of a fluorescent lamp having low-pressure mercury gas sealed therein, by inhibiting reaction with the mercury gas sealed in the lamp by coating the inner surface of the bulb with fluorescent material, consisting of activated hydroxy sulfide of rare earth elements having oxide film on the surface thereof, which is represented by a general formula (Ln1 - XL'nx)2O2S.
