Abstract

PURPOSE: To provide a green luminescent composition of improved luminance brightness under ≤100V low speed electron beam excitation, useful for green luminescent fluorescent display tubes, etc., comprising a mixture of a conductive metal oxide (or sulfide) having a specific size distribution and a specific green luminescent fluophor.
CONSTITUTION: The objective composition comprising a mixture of (a) one or more sorts of conductive materials selected from conductive metal oxides and conductive metal sulfides, with a size distribution respresented by a median and a standard deviation being 2.5W14μ and ≤0.7 respectively, and (b) one or more sorts of green luminescent fluophor selected from manganese-activated zinc silicate fluophor, manganese and arsenic-activated zinc silieate fluophor, terbium-activated rare earth oxysulifde fluophor, cerium-activated yttrium-aluminum-gallium-oxide fluophor, and europium-activated strontium-gallium sulfide fluophor. The weight ratio (a):(b) are 1:99W1:4.
