    Abstract: A method for preparing fine particles of a high brightness luminescent material improved in crystallinity; and a high brightness luminescent material prepared by the method. In an embodiment, BaMgAl10O17:Eu (BAM) as a high brightness luminescent material is prepared by a method which comprises providing an aqueous solution containing an aluminum alcoholate and water-soluble compounds of barium, magnesium and europium, adding an acid to the aqueous solution to form an acidic solution, heating the acidic solution to ca.900° C. and conducting a calcination at the temperature for a short time, and subsequently, firing the calcined product at a temperature higher than that for the calcination, for example, 1400° C. or higher. The method allows the preparation of BAM which comprises spherical fine particles having a pure phase and being improved in crystallinity, and thus is reduced in the deterioration by heat or VUV.

    Abstract: The present invention provides a method for preparing a carbon microparticle from an organic raw material having lignin as a main constituent, and a carbon microparticle obtained thereby.An aqueous solution with 5% total concentration of lignin and sodium hydroxide (the proportion in mass is 1:0.5) is spray-dried to prepare a complex microparticle. This is heat-processed under nitrogen atmosphere at 600° C. for one hour and let to cool. Thereafter, this is washed with water and further dried to prepare a hollow carbon microparticle such as those shown in FIG. 2 (b). The prepared carbon microparticle is light-weight and has an equivalent specific surface area to commercially available activated charcoal.

    Abstract: A plasma display panel having its thermal degradation and VUV deterioration reduced through enhancement of the crystallinity of luminant excitable with vacuum ultraviolet radiation to thereby attain an enhancement of luminous efficiency; and a process for producing the same. The plasma display panel comprises a pair of opposite arranged substrates and, interposed therebetween, a phosphor layer that is excited with vacuum ultraviolet radiation to thereby emit light, the phosphor layer containing spherical fine particles of a luminant excitable with vacuum ultraviolet radiation. The luminant is composed only of a matrix substance and an activator and is highly pure without having any impurity phase. Accordingly, the phosphor layer can be formed while maintaining the luminance of luminant excitable with vacuum ultraviolet radiation, so that the luminescence intensity of phosphor layer can be enhanced. Thus, there can be provided a plasma display of high luminance.
