Abstract
To provide a red phosphor red phosphor, for low-voltage electron beams, excellent in the life characteristic of its emission luminance and phosphors, for low-voltage electron beams, emitting light in various colors, the red phosphor containing SrTiO3:Pr, Al as a main component thereof is mixed an inorganic compound comprises sulfides. The inorganic compound is a sulfide or a sulfide-containing phosphor. The inorganic compound is a sulfide of alkaline earth metals.
Claims11
A vacuum fluorescent display for allowing a phosphor to emit light by irradiating said phosphor formed on an anode substrate with low-voltage electron beams generated from a cathode, wherein said phosphor is a red phosphor for low-voltage electron beams comprising:
- a red phosphor containing SrTiO3:Pr, Al as a main component thereof;
- and
- an inorganic compound comprising a sulfide.
