Abstract
PURPOSE: To provide a red luminescent composition of improved luminance brightness under ≤100V low speed electron beam excitation, useful for red luminescent fluorescent display tubes, etc., comprising a mixture of a conductive metal oxide (or sulfide) having a specific size distribution and a specific red 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 represented by a median and a stardard deviarion being 2.5W14μ and ≤0.7, respectively, and (b) one or more sorts of red luminescent fluophor selected from europium-activated rare earth oxysulfide fluophor, europium-activated rare earth oxide fluophor, europium-activated rare earth vanadate fluophor, europium-activated rare earth borate fluophor, europium-activated rare earth phosphate fluophor, manganese-activated cadmium borate fluophor, etc. The weight ratio (a):(b) are 1:99W1:4.
