説明

As the blue component of the three band lamp, BaMg2Al16O27: Eu2+ (BAM) and (Sr, Ca) 10 (PO4) 6Cl2: Eu2+ (Sr-CAP) are most commonly used. These phosphors, however, show greater luminous flux decrease than the green and red components, leading to the shift of chromaticity during lamp operation.<BR>This paper describes a newly developed phoshor, (Ba, Ca, Mg) 10 (PO4) 6Cl2: Eu2+ (Ba-CAP). Preparation method, luminescence properties, degradation behavior by 185 nm irradiation and by baking are presented. This phosphor exhibits greater stability than BAM and Sr-CAP, and yields the three band lamp with a smaller color shift.
