Abstract

PURPOSE: To obtain luminous materials giving a highly luminous red light by excitation by low-speed electron beams, which are useful for fluorescent display tube, by conferring an electric conductivity upon a mixture of a stannic oxide conductive material and a europium-activated fluorescent substance.
CONSTITUTION: At least one fluorescent substance selected from a europium-activated yttrium-lanthanum-gadolinium oxide fluorescent substance [(Y1-x-yLaxGdy)2 O3:Eu, (0≤x≤1, 0≤y≤1 and x+y≤1)], europium-activated yttrium-lanthanum- gadolinium oxysulfide fluorescent substance [(Y1-x-yLaxGdy)2O2S: Eu (0≤x≤ 1, 0≤y≤1 and x+y≤1)], and europium-activated yttrium-lanthanum-gadolinium vanadate fluorescent substance [(Y1-x-yLaxGdyVO4:Eu (0≤x≤1, 0≤y≤1 and x+y≤1)] and a stannic oxide conductive material are mixed in a proportion of 14:1W1:14 by weight to obtain a luminous material.
