What are Phosphors?
Phosphors are the material that emit the visible light that makes up the picture we see from a standard CRT based television, projector, computer monitor or the new plasma displays. In a CRT the phosphors are on the inside of the front glass and are excited by a beam of light from the cathode-ray. In a gas plasma flat display, the phosphors are on the inside of the rear glass of the millions of tiny cells or bubbles. The phosphors are excited by UV light produced by electromagnetically charged plasma in the cell.
