日本专利:东芝公司研制。阴极射线管表面的荧光物质至少有一部分是由硫化锌荧光物质涂敷的。荧光物质的到备过程是:以低于最初焙烧的温度进行两次焙烧,目的是使激活剂或共激活剂活化,以便用0.5-200ppm 的钴掺杂荧光物质颗粒。基质荧光物质包括钴激活硫化锌,金激活硫化锌,钴激活硫化锌镉和金铜激活硫化锌。 Japanese patent: Toshiba developed. At least a portion of the fluorescent material on the cathode ray tube surface is coated with a zinc sulfide fluorescent material. Phosphors are prepared by firing twice at a lower temperature than initially calcined in order to activate the activator or co-activator in order to dope the phosphor particles with 0.5-200 ppm cobalt. Matrix phosphors include cobalt activated zinc sulfide, gold activated zinc sulfide, cobalt activated zinc sulfide cadmium sulfide, and gold copper activated zinc sulfide.
