    • It is desired to provide an aluminate phosphor having a high emission luminance, a method for producing the same, and a vacuum ultra-violet radiation excited light emitting element in which the aluminate phosphor is used. A method for producing an aluminate phosphor by mixing an &agr;-alumina powder, an aqueous solution containing a cation of a metal composing the aluminate phosphor, and a precipitant that precipitates the cation, and drying and calcining an obtained mixture of precipitates is provided. The foregoing method is further arranged so that the cation is a cation of at least one metal selected from the group consisting of Ba, Mg, Eu, Mn, Sr, Ca, Tb, Ce, and Zn is provided. An aluminate phosphor in which particles of the aluminate phosphor having a primary particle diameter of 0.05 &mgr;m to 30 &mgr;m account for not less than 80 percent by mass is provided by the foregoing method.
    • 期望提供具有高发光亮度的铝酸盐荧光体,其制造方法以及其中使用铝酸盐荧光体的真空紫外辐射激发发光元件。 提供一种通过混合α-氧化铝粉末,含有构成铝酸盐荧光体的金属的阳离子的水溶液和沉淀阳离子的沉淀剂以及干燥和煅烧所得到的沉淀物混合物来生产铝酸盐荧光体的方法。 进一步安排上述方法,使得阳离子是选自Ba,Mg,Eu,Mn,Sr,Ca,Tb,Ce中的至少一种金属的阳离子,并且提供Zn。 通过上述方法提供一种铝酸盐荧光体,其中一次粒径为0.05μm〜30μm的铝酸盐荧光体的粒子不少于80质量%。
