Abstract

PURPOSE: To perform quality test in a fluorescent screen-manufacturing process by adhering a fluorescent material showing a similar luminescence by near-ultraviolet rays to the surface of a fluorescent material luminescing by electron rays, but not by near-ultraviolet rays.
CONSTITUTION: The surfaces as nucleus fluorescent material particles, luminescing by stimulation of electron rays, but not by the near-ultraviolet rays of a wave length of 200nm or more, are coated with an other fluorescent material emitting a similar luminescence by the near-ultraviolet rays of a wave length of 200nm or more. For example, in case where the first fluorescent material emitting no luminescence by near-ultraviolet rays, serving as a uncleus, is the red fluorescent material of manganese-activated zinc magnesium orthophosphate, the second fluorescent material to be coated on the surfaces of the first fluorescent material is a red fluorescent material of Eu-activated yttrium oxide, etc. The second red fluorescent material is coated on the surfaces of the first red fluorescent material with the aid of an organic high-molecular substance.
