Abstract

To obtain a fluorescent substance capable of manifesting excellent brightness characteristics without adversely affecting a cathode in a fluorescent display device under about 2000V driving voltage. This fluorescent substance is obtained by mixing SrTiO3:Pr, X (X is Al, Ga, etc.) which is a low-resistance fluorescent substance with Y2O3:Eu that is a high-resistance fluorescent substance at a varied mixing ratio. A fluorescent substance prepared by mixing a Y2O3:Eu fluorescent substance with In2O3 at a varied mixing ratio is used as a comparative example. The respective fluorescent substances are made to emit light under the same driving conditions in a fluorescent display device of the same structure and the relative luminous brightness is compared. This example is better in luminous brightness than that of the comparative example at each mixing ratio. Good results are obtained especially at (2/98) to (90/10) mixing ratio and better results are obtained at (20/80) to (50/50) mixing ratio. The fluorescent substance is closer to a red luminous color of SrTiO3:Pr, X than that of the Y2O3:Eu fluorescent substance emitting a light somewhat close to an orange color and can be used as a red fluorescent substance in a full color display fluorescent display device without causing any problem.
