Abstract

PURPOSE: To produce a fluorescent display tube which shows blue luminescence with high luminance when excited by low speed electron beam by using a luminous composition obtained by mixing ZnO with Ag-activated ZnS fluorescent substance in a specific ratio by weight as the fluorescent membrane.
