    • A phosphor powder for producing a high resolution phosphor screen and a phosphor screen are provided. The phosphor screen comprises a substrate, an infrared-absorbing layer, and a phosphor layer coated on the infrared-absorbing layer, wherein the phosphor layer comprises a phosphor powder in which a substantial amount of particles in the powder have a particle size as measured in the longest dimension of greater than 0 and less than about 5 microns. The phosphor screen may also comprise a black, infrared-absorbing substrate with the phosphor layer coated on the substrate. The phosphor powder is formed by preparing a phosphor composition, sintering the composition to form ingots, grinding the ingots to form a powder wherein a substantial amount of particles in the powder have a particle size of greater than 0 and less than about 5 microns, reactivating the powder in an inert atmosphere to a temperature of from about 500°C to about 550°C, preparing a suspension of the powder and a nonreactive organic solvent, mixing the suspension to separate particles of the powder which partially fuse during reactivation and to break up large agglomerates of the powder in the suspension, decanting the suspension to at least partially separate the nonreactive inorganic solvent and the powder, and drying the powder to form the phosphor powder.
    • 提供了用于生产高分辨率荧光屏和荧光屏的荧光体粉末。 荧光屏包括基板,其中红外线吸收层,以及涂覆在所述红外线吸收层上的荧光体层,worin磷光体层包括磷光体粉末,其中颗粒在粉末大量的粒径作为测量 的大于0且小于约5微米的最长尺寸。 因此,磷光体屏幕可以包括黑色,红外线吸收基材与涂布在基板上的荧光体层。 荧光体粉末是通过制备的荧光粉组合物,烧结该组合物以形成锭,研磨锭以形成粉末worin颗粒在粉末大量具有大于约5大于0且小于微米的粒度,重新激活FORMED 该粉末在惰性气氛下从约500℃至约550℃的温度下,制备悬浮液的粉末和非反应性的有机溶剂,混合所述悬浮液至粉末的单独的颗粒,其在激活部分熔丝和破 向上大团块在悬浮液中的粉末的,倾析该悬浮液以至少部分分离所述非反应性无机溶剂和粉末,和该粉末以形成荧光体粉末进行干燥。
