R5 Human Immunodeficiency Virus Type 1 Infection of Fetal Thymic Organ Culture Induces Cytokine and CCR5 Expression

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 alpha-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 mum to 30 mum account for not less than 80 percent by mass is provided by the foregoing method.
