Abstract
A fluorescent luminous device capable of providing a fluorescent luminous device including a non-sulfide phosphor which is reduced in resistance and emits light of a reddish luminous color. The fluorescent luminous device is so constructed that the phosphor layer is made of a non-sulfide phosphor excited by luminescence of a ZnO:Zn phosphor to emit light of a yellowish red luminous color. The ZnO:Zn phosphor is deposited on the non-sulfide phosphor.
