Optical characteristics of the phosphor screen in field-emission environments

摘要: The required luminance for information display is near 300 cd/m2 white. amount of light emitted from phosphor screen depends upon the anode voltage and electron density field emitter arrays. Field-emission to date usually do not use high accelerating but low with a great number cold electrons arrays brightness. In these situations, charge accumulations on phosphors should be minimized get long lifetimes. It found that introduction wide band-gap material oxide effective improved efficiency formation leakage path accumulated may only increase cathodeluminescent intensity also relax degradation. They are presumably due prevention accumulation surface phosphors.
