    摘要: The present invention relates to a zinc sulphide phosphor and to a process for producing same. The invention further relates to a security document or document of value, to a security feature and to a method for detecting same. The phosphor according to the invention can act as electroluminescent phosphor and thus be excited by an electrical field, and this can result in emission of electroluminescent light in the blue and/or green colour region of the visible spectrum. The phosphor can moreover be excited by UV radiation in the wavelength range from 345 nm to 370 nm, and can thus emit photoluminescent light in the blue colour region of the visible spectrum. The phosphor can moreover be excited by UV radiation in the wavelength range from 310 nm to 335 nm, and can thus emit photoluminescent light in the green colour region of the visible spectrum.

    摘要: An electroluminescent phosphor containing an effective amount of bismuth to increase the half-life of the phosphor compared to the half-life of the phosphor without the bismuth. The phosphor is produced by the method comprising the steps of preparing the electroluminescent phosphor; adding granular, elemental bismuth to the bottom of a quartz reaction vessel; covering the bismuth with a layer of quartz wool; placing the phosphor on top of the quartz wool; evacuating the reaction vessel to about 750 - 760 mm Hg and sealing the vessel; and heating the vessel to between about 500 t0 700°C for about 24 to 72 hours.
