    摘要: A plasma picture screen fitted with a phosphor layer comprising a red phosphor activated by Eu3+ shows an improved red color point (x≧0.64 and y≦0.35) and shorter decay times &tgr;1/10 as compared with the standard phosphor (Y,Gd)BO3. The phosphor according to the invention has a lattice in which the activator Eu3+ occupies a location which has no inversion symmetry.

    摘要: By adding the afterglow function to the incandescent lamp, it is made easier, in the place where the incandescent lamp is used, to recognize objects nearby in the darkness after the lamp is turned off or when the electrical power is cut off. An incandescent lamp wherein an inner surface of a glass globe is coated with a phosphorescent phosphor is provided. For the phosphorescent phosphor, there can be used a phosphorescent phosphor comprising, as a host crystal, a compound of the general formula either MAl2O4 or MAl14O25 wherein M is one or more of metal elements selected from the group consisting of calcium, strontium and barium, and utilizing europium (Eu) as an activator, together with dysprosium (Dy) or neodymium (Nd) as a coactivator; as well as a phosphorescent phosphor comprising Y2O2S as a host crystal, and utilizing europium (Eu), magnesium (Mg) or titanium (Ti) as an activator.
