Abstract
PURPOSE: A multicolor luminous fluorescent substance, capable of controlling signals and displaying multicolors, and changing the luminous color of a fluorescent membrane, prepared by incorporating a europium-activated tin oxide fluorescent substance with a copper-aluminum activated zinc sulfide fluorescent substance.
CONSTITUTION: (A) A europium-activated tin oxide (SnO2:Eu) fluorescent substance is incorporated with (B) a copper-aluminum activated zinc sulfide (ZnS:Cu: Al) fluorescent substance at a weight ratio of (A) to (B) of 9:1W1:9 to give a multicolor fluorescent substance, which is deposited on a letter segment electrode to form a fluorescent membrane. The signals to be applied to the electrode are controlled to change the luminous color by the fluorescent membrane. The particle size of the substance is preferably 0.1W20μ.
