Abstract
Nano-particles of an electrically conductive oxide adhere to the surface of particles of a phosphor for low-voltage electron beams. The average diameter of nano-particles of the electrically conductive oxide is in the range of 5 to 100 nm. The weight percentage of the nano-particles of the electrically conductive oxide to the entire phosphor is 0.01 to 10. A vacuum fluorescent display uses the phosphor for low-voltage electron beams.
